I am 33 years old and suffered a ruptured disc in my cervical spine. I am better but not well. Suggestions?

I have not had surgery and do not plan to get it. I have done physical therapy, mage, chiropractic, cervical epidural injections. I was on many narcotics, but stopped taking them when I found out it inhibits your body to heal. At that same time I got serious about taking nutritional supplements. That was the single best thing that helped, but I think I have sort of plateaued. Thanks in advance. JP
