I am facing similar issues with workmans comp. Except I had a wc surgery for frozen shoulder, torn labrum, rotator cuff tear, and had my bursa removed to make space. After the surgery, my hand was tingly... for almost a year now. Had emg, shows slow response annd also muscle atrophy in hand. Pain has extended to my arm and shoulder. Shooting pain and numbness down arm. WC says it is not related. Getting treatment through my own insurance but will soon be MMI through comp. I want my case to remain open because the TOS is related, just have not found any documentation showing that this could be from the surgery or pain pump.
