My pain in the neck and shoulder turned out to be a herniated and torn disc between my c5& 6 vertebrae. It turns out bone spurs are causing the disc to be pushed out and I am having surgery on the 9th of Dec. I tried traction and cortisone shots, muscle relaxants and a TENS machine for a year. Hopefully the surgery will finally fix it. I went in for a MRI after my arm became numb all the time.
