Complex Regional Pain Syndrome

Complex regional pain syndrome (CRPS), formerly known as Reflex Sympathetic Dystrophy Syndrome (RSDS), is a very debilitating disorder that podiatrists sometimes see. This disorder begins after a nerve injury. This injury can leave the nerves in a hypersensitive and painful state. This causes patients to have “out of proportion” pain. This means that an action or stimulus that would barely hurt a person without this condition causes excruciating pain to the person with CRPS.
The exact cause of CRPS is not completely understood. It is suspected that damage to the nerves causes problems in controlling blood vessels and sweat glands. These damaged nerves lose the ability to control temperature, blood flow, and sensation to the affected area. CRPS is more common between the ages of 40-60.

There are 3 stages to CRPS but they don’t necessarily represent an ordered progression. You could be in one stage indefinitely or start out at stage 2 or 3 without going through 1. Symptoms range from severe burning, aching to the lightest touch. The skin could become dry and thin. Pain may move further up the limb. This could progress to swelling, changes in bone on an x-ray, stiff muscles and joints. And severe forms could include a painful entire limb, muscle wasting, and contractions involving muscles of the limb.

Treatment is tough for this condition. Your podiatrist commonly will take a team approach, possibly working with physical therapy and pain management specialists. Medications could include strong pain killers, steroids, and medications for blood pressure. Physical therapy can work with applications of hot and cold for pain relief. For the pain, nerve blocks could be utilized. For more severe cases, surgery would be pursued to cut the affected nerves.
