Complex regional pain syndrome is thought to be brought on by issues of the peripheral and central nervous systems, with damage or dysfunction tending to be the leading causes. CRPS causes pain and a change in the look and feel of the affected area in terms of color, temperature, and swelling. CRPS might cause leg pain, arm pain, or issues with the hands and feet, most commonly after an injury has occurred. CRPS currently exists in two different types. CRPS-I (formerly called reflex sympathetic dystrophy or RSD) occurs without known nerve damage while CRPS-II (formerly called causalgia) occurs with known nerve damage. The treatment for both types of complex regional pain syndrome is similar. There are a number of treatment options available for CRPS, including spinal cord stimulation in Mission Viejo, CA.
