This chronic condition, also known as reflex sympathetic dystrophy, is an unexplained feeling of pain and discomfort that most commonly affects an arm, leg, hand or foot. Often, it begins in the hand or foot and then spreads to affect the entire limb.

This minimally-invasive procedure, also called radiofrequency (RF) rhizotomy, reduces or eliminates the pain of damaged facet joints by disrupting the medial branch nerves that carry the pain signals. This procedure is performed with local anesthetic.

This outpatient procedure is an injection of a steroid-anesthetic medication. The medication can reduce swelling and inflammation of irritated spinal nerves. This procedure is performed to relieve pain in the lower back and pain that radiates from the back to the legs. The injection takes only a few minutes to complete.
