Complex regional pain syndrome (CRPS) is a form of chronic pain that typically develops after an injury, surgery, stroke, or heart attack, and can affect the arm, leg, hand, or foot. The pain is usually disproportionately more severe than the initial injury.
Patients with CRPS may experience the following signs and symptoms:
The condition may spread to other parts of the body, such as the opposite limb. When changes occur in the skin and nails, the condition may be irreversible.
The exact cause of CRPS is not fully understood, however doctors believe the condition is caused by an injury to or an abnormality of the peripheral and central nervous systems.
The two types of CRPS have similar symptoms but different causes:
CRPS may also occur after a crushing injury, fracture, surgery, heart attack, infection, and sprained ankle.
Left untreated, CRPS can lead to tissue wasting (atrophy) or muscle tightening (contracture).
At Westcare Clinics, patients suffering from complex regional pain syndrome may be treated with joint and soft tissue injections, pain management techniques, and occupational medicine.
Joint and soft tissue injections, such as epidural injections (interlaminar and transforaminal), piriformis injection, sacroiliac joint injections, and trigger point injections, can help ease and treat complex regional pain syndrome. The type of soft tissue injection that is done will depend on the type, severity, and location of the pain.
