WTF are you doing that for?
when i had it done it was because i lost all feeling in my left arm from elbow to fingertips.
the funny part was the doctor was about 90lbs and 5' tall,and he grabbed my arm and said "pull your arm across you as hard as you can".so i did and i put that little fucker on his ass.then he realized i still had full shoulder strength
it sucked,but it wasnt the worst thing i have ever had done.
