That IS the point, Bobert. Some 'pinches' can be treated easier than others. Mine was relatively easy, as the MRI showed the little bone spur that was rubbing the nerve and making my right arm hurt so bad I had to sleep with it on a pillow.
I STILL can't look at a helicopter over my left shoulder without numbness starting.

*IF* they can identify the precise point, Cortisone might help..or relatively minor surgery. But chiropractors could do more harm than good if they irritate it more.
