I have chronic neck pain moderate to severe, depends on the day. At age 34 via x - rays and extensive testing , my Dr told me I have a neck the same as a 70 year old. No medical explanation for it just arthritis and possibly 3 children later triggered it. Tried over the counter pain meds but had no effect. Vicodin use to work but can't take that forever! Would love a safer alternative that is equally effective.
