What is it?

Complex regional pain syndrome (CRPS) is chronic pain that typically affects the arm or leg. It is usually triggered by an injury, surgery, stroke or a heart attack. The cause for the unproportionate pain is not fully understood, it’s thought that it could have to do with abnormality or injury to the nervous system. Over time, CRPS can cause muscle tightening and tissue wasting, causing decreased ability to move the affected body part.
