Nerve related. It hurts from the base of my neck through the meat of my right shoulder, in the arm/shoulder joint and down the right arm all the way to the wrist. I'm not too excited about the prospect of surgery but I can't live like this the rest of my life.The only thing that helped my messed up L5-S1 disc was surgery. They did a microdiscectomy and a laminectomy. Basically they cut some disc material out and ported/polished the vertebrae to get rid of the interference with the sciatic nerve. Is your pain nerve related or muscle spasm related? That would likely be a different treatment.
