Chronic vs. Acute Pain
You are going to have to differentiate between what I define as "chronic" pain, such as the pain of moderate arthritis and the natural muscle tightness, stiffness, and soreness you experience during the late stages of healing and recovery after bone breaks, sprains, and tears from the "acute" pains, which are the pains informing you that your are actively damaging or inflaming, rather than strengthening your injured parts.
Acute pains require ceasing exercise. Chronic pains are generally "workable," with proper warm-up, care, observation, and feedback.
Acute pains are the de-habilitating pains, generally "sharp" or "flaming" in nature, that accompany increasing inflammation and while damaging tissues. Chronic pains are generally characterized by dull aches, stiffness and low to moderate grade pain. Chronic pains can build-up to an "acute" level during and after exercise, requiring a cessation of exercise or extended recovery time.
When to Start and Stop
Our goal here is to first, carefully work up the flexibility and range of motion of the injured parts, then add some strength through walking. We will then build up our walking distances and pace to eventually build up the endurance of the areas afflicted by injury and chronic pain. We are aiming to do this without sparking acute pain or actually re injuring the part. This means knowing when to stop exercising is as important as knowing when to start exercising.
Rest is as Important as Work
First and foremost, make sure you have allowed the injury to properly heal and rest after the injury. Not letting an injury heal properly before starting exercise is a recipe for long term chronic pain. Bone breaks, sprains, and every other injury have pretty well established 'average" required times of healing and rest before physical therapy can start. Consult your medical professional for average healing times for your specific injury. Healing times can vary considerably between individuals. Consult your doctor for the proper time to begin range of motion, stretching, and light exercise after an injury.
Starting a therapy program after injury is almost always painful and will generally spark some degree of swelling and inflammation. Anticipate that your injured parts will over-respond with pain and irritation when you first start working them. Start slowly. Carefully monitor the injured part's responses to your first application of range of motion and light exercise.
Note the role and effectiveness of anti-inflammatories when starting stretching and light exercise. If you have reduced pain and anti-inflammatory use prior to beginning stretching and light exercise, note any changes or increase in pain and inflammation caused by the new activities.
You have two options to treat increased pain and/or inflammation. First, you can cease, reduce the exercise/stretching, and increase the time between exercises. Second, you can increase anti-inflammatory use prior to and after the exercise/stretching session.
My point here is that sometimes slowing or stopping exercise sessions, or increasing rest between exercise sessions will get you to your goal quicker than pushing on. This is just as true when you are healing as when you are hiking a long difficult route.
Needing extra recovery time can be especially important when you are just beginning work on injuries and recovering fitness. Our goal is to use range of motion and light exercise to gradually diminish the amount of pain we experience for a given amount of exercise, though we may have to deal with increased pain and inflammation for a while before we actually achieve a decrease in pain for a given amount of work.
The exercises that are required to strengthen you also require recovery time.
Ignoring acute pain and trying to work through acute pain can be a recipe for physical disaster and long term disability along with perpetual extreme pain. The key is knowing when to strategically back-off and allow your healing injuries to rest and recover, and when it is safe to push your program harder.
This is why developing the experience and self-knowledge to differeiante between an acceptable level of chronic stresses and strains produced by your stretching and walking program from dehabilitating acute pains the risk further injury and disability is so very important.
If you have been sendentary while healing and recovering, or if you have just been sedentary, you are also going to have to deal with the metabolic stresses and fatigue that the trajectory of this program is going to cause.
Be prudent. Understand that rest is just as important as work during the healing and recovery process. Heck, healing and recovery from your exercises themselves is required. Your critical job is going to be properly judging whether work or rest is approiate for every particular situation.
Anticipate Changes
For me the important changes are marked by the points where chronic aching pains start sharpening up into flaming acute pains. I can generally anticipate that transition before it happens, as the chronic pains begin to sharpen, which allows me to moderate the exercise to prevent chronic pains from going acute.
Don't let you enthusiam hurt you. The whole point of these exercises is to make you stronger. If you work your injured or lazy parts beyond their capacity, you are risking serious long-term injury, and risk making yourself weaker for a very long time.
This means that you are going to have to carefully monitor your pain responses to stretching and exercise and be sensitive enough understand, to feel, when your chronic pain is transitioning to acute pain. Then you must be smart enough to stop or moderate the exercise sufficiently to prevent the onset of acute pain to prevent further injury and prolonged disability.
The key to success is sensitivity and experience applied consistently over time. Focus your enthusiam into a dicipilined schedule moderated by accurate self-analysis. You must learn how to accurately identify the type of pain you are experiencing, and feel when it is deteriorating so you can slow down or stop your activity. You must prevent injuring yourself further and/or experiencing extended and painful recovery periods between exercise sessions.
There is no reason to rush. When your injured parts say NO, no means no! You just need to be able to properly interpret your body's language of pain, and be able to differentiate between the normal pain of beating yourself back into shape from the acute pains caused by overworking injured parts.
Managing Chronic Pain
The goal is to build strength and flexibility while maintaining steady, if not decreasing levels of chronic pain for increasing amounts of work. Chronic pain is not uncommon after injuring a joint. Persisting chronic pain following severe injuries to ankles, knees, hips, backs, and shoulders can be managed through flexibility, aerobic, and strength exercises.
Chronic pain must be monitored and exercised within limits. The limit is when the pain starts transitioning to acute pain. Your initial judgment, to continue or stop, will be validated by two aftereffects. The first effect is the level of pain that endures after exercise is stopped. Second, and related to the first, is how long this elevated level of pain persists after the exercise is stopped.
How the injury responds after the exercise session is telling. The maximum effects will generally manifest themselves the next day after your walking and stretching program. This is a vital signal of its condition. If the pain has substantially increased, or even gone "acute," then your judgment of the levels of chronic pain you experienced during stretching and exercise was incorrect, and you over-did it. Now you must rest and recover until you have reduced the acute pain back to chronic levels before restarting exercise. Anti-inflammatories may be indicated before and after the exercise session to maintain reasonable levels of pain during the exercise and to keep both inflammation and recovery times down.
Recovery sometimes demands stopping all exercise. Sometimes it demands starting exercise. Only you can accurately identify the proper balance between exercise and rest to build flexibility and strength by judging the type of pain you are experiencing, and how the level of your pain is being influenced by stretching and exercise, and how long it takes you to recover from a given amount of exercise.
The key is going to be working out a schedule that strengthens your injured parts without re sparking the injury, and triggering extended increased pain after exercise. Professional consultations between you, your doctor, and a physical therapist can be productive in working out a program schedule.
Rest and Recovery
The fact is that Rest and Recovery from exercise are just as important as the exercises themselves. My "standard" interval between all exercise sessions, be it aerobic or weights, is one day working, one day off. The off day from running is the weight training day, and the day off of weight training is the jogging day. This is my goal and schedule during periods of optimal conditioning.
When restarting an exercise program or recovering from an injury I may require two or more days off between exercise sessions to allow the inflammation and pain to recede back to my current level of base-line pain. The interval of time it takes for your injury (or your body) to recover from an exercise session sufficiently to begin another exercise session is your Recovery Time.
The goal is to gradually bring our Recovery Time between exercises back down to one day, while gradually increasing the duration and difficulty of the exercises back to our normal high level of fitness.
The key to identifying the proper decision between rest and exercise is going to be based your understanding of the meaning and consequences of the pain messages and information your body is sending you, as distinct from your personal desires and goal of working a successful exercise program. You must know the differences between chronic pains that are workable, and acute pains that are not. You must have the discipline to stop working when your body requires rest.
This understanding can be built thorough carefully monitoring of your level of exercise in reference to your body's immediate and medium-term responses. The pain of overworking a healing injury can continue to intensify the day following the overwork. In this case you may want to increase the recovery time to two days between exercise sessions, and begin decreasing the intensity of the exercise session until only one day of Recovery Time is required.
Don't allow your desire to get back into shape overrule your body's need for rest, recovery, and proper healing time. I have seen as many people prolong injuries through overwork as through under work.
You are going to have to find the balance perfect for you.

Pain Control
The most painful part of my most recent injury (frostbite) are the patches of dead, dying, and damaged skin with their withering nerves. On the other hand, re growing the skin has been as painful as feeling it die. This pain equals and ocassionally exceeds the various "class 10" pains I have previously experienced, both in intensity and duration. Serious pain control is required.
My secondary injuries are the insults to the bones, muscles, and soft tissues, composing the "structure" of my foot, caused by the same lack of oxygen that killed the skin on my toes. Overall, the "external" recovery of my skin has been about as painful as its death was. The "internal" recovery of the soft tissue, the healing of the bones, ligaments, tendons, and muscles in the front of my foot have a fierce dull aching pain similar to that I experienced during plantar facisits.
The damaged nerves in the skin are recovering sensation and growing as nerves do, through pain. The skin growth at the tip of my toe is interesting: I am growing skin with nerves and blood vessels. Quite interesting "sensations," unique variations on the theme of pain, for those you who are unfamiliar with nerve pain. Flaming, burning, and stabbing would be common adjectives.
The structural damage is reminiscent of the dull pains experienced while healing from a broken bone, much like the screaming dull pain of plantar fasciitis. This is a pain reminiscent of tissue being pulled off the bone. The nerve pains in my toes are similar to those produced by a herniated disc in one's back.
All of these pains are quite distracting during the day, and have made sleeping quite challenging. The exhaustion and psychological stresses of extended periods of constant pain are real impediments to healing. This wide spectrum of injured tissues and types of pain demands a well thought out pain control program.
Different Pains, Different Drugs
It is vitally important for both physical and mental healing to control pain. Extreme pain can significantly slow the healing process, and add extra dimensions of suffering to your injury from the resulting lack of sleep and stress.
The searing nerve pains from skin degradation on my toes are complemented by deep aching pains indicative of the"structural" damage done to the front footpad and toes. The nerve pain requires the strongest painkillers for extreme pain, while the "structural" pains traditionally respond well to anti-inflamatories and mild painkillers.
The multi-faceted nature of this injury requires that I track, treat, and medicate the different aspects of the injury as if they are different injuries, and carefully monitor the effects of the overlapping pain programs on each injury.
The extreme pain of nerve and skin degradation requires powerful narcotics. In my case I was taking 30 mg Morphine like skittles during the early phases of the injury, with days off to prevent tolerance and addiction. The structural issues, consisting of the soft tissue and bone structure problems, respond better to anti-inflammatories than pain killers.
During the initial stages of the injury the narcotics suppressed both the skin and structural pains. But as the healing progressed and I began walking on the injured footpad and foot structure, the nature of the structural injury indicated that anti-inflamatories would better address this injury than narcotics alone.
Both the narcotics and anti-inflammatories can be very beneficial to healing and recovery from orthopedic injuries, but each must be properly targeted to achieve the best results, and both narcotics and anti inflammatories have many drawbacks that require both be carefully monitored.
Great care and close monitoring of your injured part's responses to drug treatments for safety and effectiveness. Proper use of drugs can speed healing and aid your recovery of fitness. But you must carefully monitor the status of your injury without drugs to properly determine when you are actually ready to begin range of motion, stretching, and light exercise. You may feel like you can run far and long if you are all hopped-up on powerful narcotics when you should not even get out of your chair.
The onset of exercise must be carefully managed so you can get the most out of your exercises as well as your pain and inflammation control programs.
Drugs
Anti Inflammatories
The majority of backpacker's most common injuries involve sprains, tears, and a wide selection of soft tissue joint injuries. Many of these injuries can be treated on the trail with supplies on hand in a well packed first aid kit. My favorite on-trail anti-inflammation asset is the ice cold stream.
Ice cold High Sierra streams are excellent for reducing inflammation and swelling after injury. Immerse the injured part in the ice cold creek for as long as you can, then remove it. Repeat for as long as possible. Ice cold creeks are also good for sealing cuts. Just be careful not to fall in!
The cold water reduces swelling.
Soft tissue injuries also respond well to anti-inflammatories, but both of the classic anti-inflammatories, Ibuprofen and Acetaminophen, have serious side-effects, and these powerful drugs affect different people differently, so show caution when using these drugs until you know how they particularly affect you. This family of anit-inflammatories is known as NSAIDs.
Ibuprofen, Acetaminophen, and Aspirin are but a few of this large and popular group of drugs known as Non-Steroidal Anti-Inflammatory Drugs, or NSAIDs.
NSAIDs are very powerful drugs that can screw you up as easily as they reduce inflammation. Inform yourself about their side effects, monitor their effects on your system, and give yourself occasional sustained vacations from their use.
Ibuprofen must be taken with food to protect your stomach, and has a 24 hour limit of 2400 mg. It is very effective against low to moderate chronic pain
Acetaminophen is dangerous if mixed with alcohol, and is hard on your liver in any case. It is less effective than Ibuprofen for me.

Narcotics
High levels of two distinct types of pain caused by my frostbite require a serious pain management system. Both the high level of nerve pain and the intense structural pains must be effectively controlled for efficient healing and restoration of physical capability. The narcotics will cover all the pain with a broad brush, but the narcotics will not reduce the internal swelling of the foot. The anti-inflammatories will.
Narcotics must be treated with great care. Narcotics quickly lose their effectiveness as your body rapidly develops tolerance. For this reason I have a two part strategy for narcotic use.
Use
First, I use the minimum dose necessary to break the grip of extreme acute pain, and only when the pain is bordering on unbearable. My goal is to eliminate daytime use of narcotics as soon as possible, preserving the most powerful drugs for when I need them the most, which is generally at night for sleep, to rest. This reduces the daily dosage to night hours. This makes for some damn uncomfortable days. Such is the cost of maintaining narcotic effectiveness.
Second, I try to maintain a two-days on, two-days off narcotic schedule. This allows me to build up the level of narcotic in my blood by the second day of nighttime use to "take the edge off" of the extreme pain. The next day, the first day off the narcotics, is characterized by increasing pain, with the second day off of narcotics again revealing my true pain status without pain medication. From that point of assessment I monitor the pain trying to delay restarting the narcotics for as long as reasonably possible.
Early in the injury I restarted the narcotics immediately after the second day off. As the injury reached the healing stages I have been able to expand the narcotic-free periods up to 4 days before lack of sleep and extreme pain again clearly indicates narcotic use is necessary.
This strategy avoids developing a tolerance, avoids addiction, and avoids the exhausting effects extended narcotic use has on the patient's metabolism.
Misuse
If you screw up with narcotics they will lose effectiveness while simultaneously exhausting you. This will leave you fully exposed to extreme pain while dehabilitated by both injury and exhaustion, and no longer protected by the narcotic effect. I experienced this particular version of living hell while recovering from a herniated disc in the late '90s...it sucked so bad that it is hard to describe.
My point is that you must carefully monitor your drug use in reference to your level and type of pain. Take the proper type and amount of drug that properly addresses your injury. Stop taking pain killers as often as possible, and push your drug free periods for as long as possible. My drug free periods allow me to "clean out," and get a clear picture of my level of pain without narcotics, while helping to keep the narcotics effective for the pain.
Balance of Powers
My assessment of the different aspects of my injury requires that I constantly re balance my meds and exercises for optimal pain management as the injury heals. This assures that you do not over-rely on meds, which will keep them effective when you need them during the progress of your recovery.
My point is that if you only rely on drugs for pain management you are in deep trouble. This section on physical preparation is based on the fact that exercise and flexibility are the best pain management system of all. You will find that the amount of exercise you can perform at a given level of pain will constantly increase. These are simple facts about the brutal nature of healing. Though I'm vying to make this as "vanilla" of a backpacking site as possible, I've got to tell the truth about my healing, even if it's illegal and not politically correct. I owe y'all the truth.
During the two days off of narcotics I used "alternative" medicine that worked really well. Honestly, I used alternative methods of pain control to morphine that were truly amazing. Let me explain.
Morphine puts up a "wall" between me and the pain, but morphine never minimizes the pain. It's the same pain with or without morphine. I can still "feel" the full force of the pain on the other side of the "wall" put up by the morphine, and the morphine induced metabolic exhaustion makes the "morphine wall" both metabolically expensive and short-lived.
Short-lived in that the morphine does not last long,takes more and more morphine to maintain the wall, and therefore morphine must be stopped sooner than later to prevent ineffectiveness and addiction. Narcotics are great, but have serious problems and liabilities effectively moderating long term pain. I found something quite intriguing.
A friend of mine made this pot "elixir" shit (boiled down weed solution suspended in glycerin?) that actually reduced the frkn pain. This elixir did not just put up a "wall" against the pain, as does the morphine, but actually reduced the pain at its source. I kid you not. Nothing else has reduced the source of the pain, except time and exercise.
This had a series secondary benefits. When taking the pot elixir my morphine use was considerably reduced, and this reduction eased the drug load on my metabolism. If you have never done narcotics before, it puts a heavy load on your metabolism.
As the skin and nerve damage heals my narcotic use declines. Less skin and nerve damage means more and longer exercise sessions, which directly confronts and inflames the structural damage in the front of the foot.
The evolution of my healing trajectory has brought about greater stretching, walking, and finally I am throwing in bits of jogging. These changes allow reduced narcotic consumption but inflame the structural problems, the soft tissue injuries the frostbite caused in the whole front of the foot.
This requires I increase my anti-inflammatory consumption to accommodate the increasing stress exercise has brought to the front footpad's structural elements.
At the end of a day of exercise I find that the exercise seriously increases the pain in the structure of my foot, which is also accompanied by screaming pains at the dead tip of my toe. This confluence of pains resolves themselves quickly half-way through the day after exercise that triggered them, leaving me ready to repeat the exercise the following day. I am moving closer to an acceptable recovery time between exercise sessions.
The ultimate goal of this healing program is pain free fitness and exercise, which also means drug free. I am constantly moving towards this goal by increasing exercise while decreasing medication at every possible opportunity.
Exercise and Drugs as Pain Management Tools
This drop down in narcotic drug use was my response to the reduction in the duration and extent of the physical locations that I'm experiencing excruciating nerve pain. The reduction in pain was accelerated by stretching and exercise. Your recovery should follow the same positive pattern, independent of your level of pain and injury: when the injured part's inflammation and pain decreases you should increase the work load, decrease the medication, all while carefully monitoring the injury's response to the changing conditions.
Natural healing and reduction in drug use can be accelerated by carefully engaging stretching and walking therapies. Though starting physical therapy can be very painful, the benefits of engagement have again and again brought about an overall reduction in my pain and inflammation for increasing gains in strength, flexibility, and endurance. Less pain means more work, and more work for less drugs. Always follow this program when you are healing and recovering from injury.
The trajectory of healing can also go the other way. Inflammation and pain can increase during exercise, shortening the exercise sessions and calling for more anti-Inflammatories and pain meds. This brings out an important point: Always note the general "direction," or trend of your pain, endurance, and flexibility. If your pain during exercise is increasing, and your recovery periods between exercise are increasing, you may need to stop or slow your program down for a while. Beside carefully watching for chronic pain degrading into acute pain, increasing levels of chronic pain during your recovery may be telling you to slow your program down a bit.
Though the tips of my toes still go "off the hook" on a regular basis, the overall duration and extent of pain throughout my foot has diminished, especially when measured against my capability. I am aggressively using these healing opportunities to get reduce the morphine and increase the intensity and duration of my exercises. So I did. Reduction in nerve pain along with slow wound healing called for an increase in exercise. This increase in exercise triggered greater structural pain in the footpad, which required more Ibuprofen.
The structural pains consisting of the pains of the degraded muscles, tendons, and ligaments in the front of the foot (the front footpad) respond to long distance walking therapy (3 to 5.5 miles, hills) with extreme dull "chronic" pains. Treating these "chronic" structural pains with Ibuprofen has been quite successful. These pains are naturally receding more quickly after exercise sessions, and the pain experienced the day after the exercise session is diminishing.
As soon as I narrowed the recovery time to one day off between walking sessions, I began jogging sections of the trail.
Increasing Ibuprofen while reducing overall use of morpheme has been critical for to prevent and reduce inflammation during exercise, and has helped to shorten my recovery time between exercises. These chronic pain aspects of the injury require, and respond well to powerful anti-inflammatories. I have found that 600 mg of Ibuprofen before and after my exercise sessions has been working well. As I continue to "feel" better during and after turning my 3.5 mile walks into 3.5 mile jogs, I will reduce the "before and after" ibuprofen doses.
As I increase my mileage towards my goal of seven mile runs, I know this cycle of increasing and decreasing inflammation will continue. I will have to constantly monitor my body and alter my distances, recovery time, and drug regimes in response.

Secondary Considerations
The inactivity and reduced activity caused by injury, in my case the first four months of almost complete inactivity following the frostbite injury, has the potential to reactivate and weaken previous injuries. You will find that new injuries can inflame old injuries, and inactivity degrades everything. This is the situation that confronts anyone who is beginning a fitness program after being sedentary for a considerable period of time.
In my case the extended period of inactivity caused by frostbite has really fired-up my previous knee, hip, and back injuries. You must consider your particular situation and previous injuries. The longer I sit static, the worse every old injury feels. Every day of inactivity is like having my knees, back, and hips beaten with a club. Add to these effects the loss of general fitness caused by eight months of inactivity, and these factors require a considered approach to restarting stretching and light exercise.
The good thing is that the irritations of these previous injuries are also addressed by the anti-inflammatories and pain killers.
Like me, you should be carefully monitoring the pain response of all my injured parts to my carefully applied stretching and walking therapy. I compare my "normal" baseline level of static pain with the pain caused by exercise and stretching.
I have noted a steady increase of strength and endurance for the same amount of pain as I continue to stretch and exercise my foot by walking.
I have been steadily reducing the use of narcotic pain medication as exercise increases, though my use of anti-inflammatories has increased.
So far, so good.
As the walking and stretching programs continue to make progress I will continue jogging longer sections of my walk, and extending the overall length and elevation of my walk.
We're on our way back.
Next we will begin to put together a well-rounded aerobic and weight lifting program that will ease our transition to carrying a heavy pack on steep inclines at high elevation.
