In 1998 I was diagnosed w/ CTS. I underwent surgery and some symptoms went away. I still had psin and swelling and "nerve spasms". I was told there was nothing else they could do. In 2007 my hand became dramaticlly worst. I was rediagnosed with CTS and they performed another release to correct the problem. Since then my hand is always swollen, either hot or cold, constant pain and major "nerve spasms". The Dr now thinks it is RSD or major median nerve damage. They did a 3 phase bone scan and my bone is within the normal range. What else can I do to get the correct diagnosis?
