Complex Regional Pain Syndrome (CRPS) is a chronic neurological disorder that often affects the the lower leg or foot, but can also impact the arms and other parts of the body. Also called Reflex Sympathetic Dystrophy (RSD), the condition can cause excruciating acute pain. Unfortunately, CRPS is still poorly understood, and significant research is still underway to learn more about its causes, symptoms and how to treat it.

CRPS is a chronic neuro-inflammatory disorder that generally affects one or more limbs, though it can happen in any part of the body . The condition causes the nervous and immune systems to malfunction in response to tissues damage, which causes nerves to misfire. A damaged neurological connection then becomes continuously more faulty and leaves the affected area in constant pain. CRPS also creates an abnormal immune system response that magnifies the pain in the affected area.
The levels of pain and outward visual CRPS symptoms can range dramatically from person to person, and although significant research is ongoing CRPS is still poorly understood.
The majority of research on CRPS suggests that in 90 percent of cases an initial injury permanently damages pain receptors in the affected area, and that causes disrupted communication between the injury and the brain .
Common initial injuries may include: fractures, sprains or strains, soft tissue injuries (such as burns, cuts, or bruises), limb immobilization (such as being in a cast), surgical or medical procedures, heart disease, degenerative arthritis, stroke, nerve irritation, shingles, and breast cancer.
The list of possible CRPS causes is constantly growing, which reflects that the exact mechanism of how CRPS develops is not well understood.
As noted above, CRPS is also often referred to as Reflex Sympathetic Dystrophy syndrome (RSD). Though many consider the terms interchangeable, RSD is more accurately used to describe a specific condition: Type I CRPS.
The two forms of CRPS, Type I and Type II, have near-identical symptoms, but they’re differentiated by their causes .
Despite these clear differences, RSD is still often used to describe the symptoms associated with either form of CRPS. When CRPS affects the upper limbs following a stroke, it is called shoulder-hand syndrome.
CRPS symptoms vary widely in intensity . Along with physical symptoms, nerve damage may correlate with an individual person’s emotional state, which affects the level of pain he or she feels. High levels of stress or anger, for example, can significantly increase many CRPS symptoms.
Common symptoms may include:
In some cases, CRPS pain can be managed using a range of over-the-counter and prescription drugs . These include but aren’t limited to: antidepressants, non-inflammatory steroid medications, muscle relaxers, narcotics, compound creams, medicated patches and diabetic neuropathy medications.
Before considering surgery, doctors may also attempt treatment using a sympathetic nerve block. This involves a spinal injection that’s intended to block pain transmission to the brain. All non-surgical pain management options must be executed under the close supervision of a doctor.
If medications or nerve blocks don’t resolve CRPS symptoms, surgery may be required to alleviate the resulting pain. The least invasive option involves locating the exact nerve causing the issue and removing or detaching it .
The most invasive and life-altering procedure used to treat CRPS is amputation of the affected limb. Most doctors oppose the idea of removing a limb because of nerve damage, but there are cases for which amputation may be the best option .
Unfortunately, there have been multiple CRPS cases in which an amputation lead to poor results. Even after removing the affected limb patients sometimes still suffer the same pain via the phantom extremity.
Anyone suffering from CRPS should consult regularly with their doctor to determine which treatments are best suited to their needs..
CRPS recovery options depend on the affected limb or limbs. For example, recovery for an arm affected by CPRS involves immobilizing the arm to limit its use while keeping it safe and comfortable.
Recovering from CRPS on the lower leg or foot is more challenging. The CRPS patient must find ways to walk with only slight pressure on the affected area. There are only a handful of options for mobility when the lower leg or foot is damaged by CRPS:
Canes and crutches literally keep the hands full, which means a person using them has limited or no use of their hands while standing or walking. Because there is no direct cure for CRPS this means people using crutches will have their hands full for life. Struggling with crutches is not an option for anyone who has to care for themselves or others. Crutches hinder a person’s ability to do laundry, cook food, take out the trash, walk the dog or numerous other day-to-day tasks.
Wheelchairs are alternatives for those looking for long-term mobility options. Wheelchairs allow the CRPS patient to keep weight off the foot, but they’re bulky and difficult to maneuver. They may also require many additional modifications to your home and routine, such as ramps that go around or over stairs, to be useful.
Knee scooters give users more freedom and versatility compared with wheelchairs, but they are cumbersome and challenging to use in tight spaces. Knee scooters also have limitations because they require use of your hands to steer and balance, and because they can only be used on flat surfaces.
The last and most revolutionary lower leg and foot recovery device for CRPS patients is the iWALK hands-free crutch. The iWALK is strapped directly to the leg and takes weight off of the injured lower leg or foot. This makes the hands available for everyday tasks. The compact, lightweight design of the iWALK makes it easy to use in small spaces, for walking up and down stairs, and even in the shower.
Though CRPS affects only a small number of people, it doesn’t mean you have to suffer alone. Support groups for those with CRPS offer ways for patients to work through recovery and also help others dealing with the same kind of debilitating pain that’s caused by this troubling condition.
The Reflex Sympathetic Dystrophy Syndrome Association (RSDSA) compiles extensive resources for those with CRPS. One of their members will contact you and help you find a local group suited to your specific situation.
This site has complied numerous links to RSD and CRPS support groups in both North America and Europe.
A support group for anyone suffering with CRPS/RSD. Members are encouraged to ask questions and share stories.
Burning Nights is a site dedicated to helping CRPS sufferers. The site offers a number of support resources to help with the overwhelming aspects of this condition.
CRPS is a challenging-to-understand chronic disease that requires in-depth research and understanding to productively survive with its diagnosis. Surgical and non-surgical treatments are available for CRPS/RSD recovery, but each should be considered carefully with a doctor’s careful input. If your lower leg or foot is affected, it is important to find a mobility device that fits your lifestyle.
