The surgery is for the impingement. My acromion (bone at top of shoulder) curves downward and needs to be shaved down, the tendons have been damaged from rubbing against it and may need some cleaning up, and he is going to surgically release the adhesive capsulitits, then I'll be hooked up to a machine that will manually moved my arm/shoulder about. Totally seperate from the brachial plexopathy, according to Neurologist.
