Reflex Sympathetic Dystrophy (RSD) or Complex Regional Pain Syndrome (CRPS)
This is also called phantom limb pain. This can occur after injuries, surgeries or for no apparent reason. The symptoms can be life-shattering. Oral anticonvulsant medications can reduce the pain, as well as desensitization physical therapy and stellate and thoracic sympathetic ganglion blocks. Recent advances in medical technology allow pain specialists to provide pain relief through implantation of spinal cord stimulator when all else fails.
