yup....tried 6 or 7 over the yrs along with DO's and acupuncture, massage, phys therapy. no luck way before I went the drug route. I recently had been very deconditioned and my high blood pressure was problem. I did not want to add more drugs i tried swimming slowly and aqua therapy and hanging upside down from gym equipment....apparently I did more harm than good. honestly, cranial sacral therapy and these various injections are the only things that have helped my cerv disc issues. diandr
