It occurred 7 years ago, and am still recovering. The
pain from my
neck to my finger tips can be terrible on some days. Fortunately, the surgery itself was not invasive. Small cut at the neck line, that is barely noticeable now. Recovery wasn't bad either, except for the pain in the arm. The surgeon did tell me, and continues to tell me, "it was nothing he did!" Thus, I don't know what happened! ;-( Drill the doctor with as many questions as you can.
