Three years ago, I was in an auto accident. I never experienced pain before. But, this was unusual. Upon getting out of bed, up from a chair, or doing certain floor exercises, I would experience a dull pain in my side, as if a metal rod was digging into me. I had different diagnoses form 2 chiropractors and an acupuncturist. One said I had a disk problem. The other diagnosed it as a tilted hip. Chiropractic treatment and acupuncture afforded little benefit. After 6 months of each, the conclusion was "learn to live with it." As a favor to a friend, I was asked to pick up some glucosomine, for her. I purchased CetylPure. But she said this was not what she wanted. Not wanting the trouble of returning it, I started taking it, myself. In a matter of days, the dull pain, very suddenly and unexpectedly just disappeared. Nearly a year later, I don't even remember what side of me it was on. I told another friend about it. She was about to undergo surgery for a painful shoulder condition. She purchased CetylPure. Two weeks later she told me she was 90% improved. Before finishing the bottle, she called off the surgery. She feels great.
