Thanks everyone. My husband's surgery went well. The doctor said he had a lot of nerve damage and a bunch of scar tissue mixed into the nerves covering the rib. He cleaned that up, removed the rib, and cut the nerve that would have caused the RSD if he had it. My husband can finally feel his arm again like it should normally feel. His nerve pain is gone. Now he is just dealing with the pain of the surgery, and getting his shoulder moving again.
