My fiance has that, and he sees a neurologist for it. His symptoms include: arms fall asleep and blood flow stops while he is sleeping, myoclonus as he is falling asleep, and intermittent grip strength problems, particularly in the right arm. Sometimes, when he wakes up he can lift his right arm using the other hand and it drops back to the bed, dead weight. Then he says it's odd to feel the blood flow returning to the arm.
He has not had to have surgery, yet, and he does exercises using one of those hand-held squeezers while he is watching television. He is 33, and he's had this since he had a bike accident when he was a teenager. It does not affect his employment yet, and we hope it never will.
Look for a good neurologist, preferably someone who specializes in the thoracic area.
