Need your input please. So it's been almost a month of non-stop pain. I have a herniated C5, C6, and C7. The C6 is pinching a major nerve down my left arm and I have lost about 75 percent movement. I have tried mckenzie exercises, heat and cold therapy, cortisone shots and going to start physical therapy. But the pain exists majorly and I'm not going the chiropractor route and surgery is a last option. Any exercises or recommendations?
