Complex Regional Pain Syndrome (CRPS): Symptoms, Causes & Types

RSD, also called complex regional pain syndrome, is a neurological disorder affecting the bones, joints, muscles and skin. The condition is painful, chronic and progressive, according to NeurologyChannel.com. It usually starts after surgery or injury on a limb.

Types

• There are two types of RSD. Type 1 involves no nerve injury, while Type 2 involves some nerve damage.

Causes

• Cerebral lesions or heart disease may cause RSD. Other causes include infection or trauma to the limb.

Symptoms

• RSD starts with swelling, burning and sensitivity to touch in the affected limb. It progresses to muscle stiffness and early bone loss, then may spread to other limbs.

Complications

• Bone, skin and muscle atrophy may occur due to reduced limb usage. Depression may be caused by RSD, as with any chronic illness, NeurologyChannel.com says.

Treatment

• Treatment of RSD is based around controlling pain. Painkillers or physical therapy may be prescribed to help patients deal with the disease.
