Abstract
|
|
|
|
Complex regional pain syndrome (CRPS) type 1 is characterized by the presence of pain, which is severe, diffuse and associated with allodynia, and is also associated with autonomic and trophic changes. The sensitization phenomena of CRPS also cause allodynia and itching, as well as pain. These symptoms are the issues associated with the treatment of CRPS. Under normal conditions, an antagonistic interaction exists between the pain and itching, but the patterns of peripheral and central sensitization phenomena for the pain and itching are very similar. The chronic pain and chronic itch have similar characteristics in their developmental and therapeutical principles. Herein, our experience of 2 cases of CRPS, which showed improvement of these facial symptoms after sphenopalatine ganglion radiofrequency thermocoagulation, but were not controlled by spinal cord stimulation or other conservative treatments, is reported.
