5 Facts you should know about

Complex regional pain syndrome

Complex regional pain syndrome (CRPS) is a form of chronic pain that usually affects an arm or a leg

It typically develops after an injury, a surgery, a stroke, or a heart attack

The pain is out of proportion to the severity of the initial injury

It is believed to be caused by improper function of the peripheral C-fiber nerve fibers that carry pain messages to the brain

Most illnesses are mild and recover over months to a few years as the injured nerve regrows
