Sometimes patients with Wilson’s Temperature Syndrome have scars on their wrists where they have undergone surgery to release the ligament that overlies the carpal tunnel. The carpal tunnel is the bony tunnel at the base of the hand through which many of the hand’s most important blood vessels, nerves, and tendons pass. The Carpal Tunnel Syndrome surgery is done to release the pressure that results from fluid retention in the tissues of the confined space that causes pinching of the nerves, and numbness and tingling of the hands. Carpal Tunnel Syndrome has long been associated with hypothyroidism. Again, however, DTSF is commonly overlooked because of over reliance on thyroid hormone blood tests. A patient presented to my office with a scar on her right wrist and numbness and tingling of her left hand. The scar on her right wrist was from the successful Carpal Tunnel Syndrome surgery that had relieved the numbness and tingling of her right hand which she had had previously. When I first saw her, she was having the identical problem with her left hand. She had already been scheduled for surgery that was to be done thirty days after our first meeting. Since her related symptoms, signs, and story were so characteristic of Wilson’s Temperature Syndrome, it was recommended to her that she postpone her Carpal Tunnel Syndrome surgery until after a therapeutic trial on thyroid hormone treatment. Within the month the numbness and tingling of her hand resolved with normalization of her body temperature patterns and she canceled her Carpal Tunnel Syndrome surgery.
