Sometimes sympathetic nerves can continue to transmit pain even after healing from surgery or injury, which is known as Chronic Regional Pain Syndrome. (These nerves take part in regulating everything from neuropathic pain to sweating, body temperature) When this happens, patients experience severe burning pain, swelling, and changes in skin color, texture, and temperature. A Lumbar Sympathetic Block is used to reduce the symptoms of CRPS in lower limbs. The injection involves a combination of an anesthetic medication plus a corticosteroid which is injected near the spine to block the nerves. #chronicpain #pain #CRPS #Causalgia #RSD #Swelling #leg #hands #lumbar #sympathetic block #painblock #painspecialist #drpriyarathi#
