Sympathetic Nerve Blocks

Sympathetic nerve blocks reduce the transmission of pain signals from sympathetic nerve roots to treat chronic pain. Sympathetic nerve blocks are typically used to treat chronic abdominal, pelvic, or rectal pain, and they are also used to treat Complex Regional Pain Syndrome (CRPS), also known as Reflex Sympathetic Dystrophy (RSD) in the arms or legs. These injections do not usually use steroids, so they can be administered more frequently, if needed, to control pain. In some cases, sympathetic nerve blocks may also be used diagnostically to see if someone might be a good candidate for a spinal cord stimulator.
