Vvv-I had a cervical discectomy and I have no more pain in neck, so mine worked for me. I was really in pain and suffering from headaches. They are all gone!! Now I have a lot more back issues in other areas. DDD, arthritis in spine, facet syndrome, and on tons of pain med just to deal with life. About 3 weeks ago started getting pain in backside and down back of legs and in feet, not sure what to think. I have been trying to get off pain patches from 100mcg to now 12mcg. Not sure if the pain patches were coving up other issues that I could not feel them.
