You sound desperate for relief and I can understand where you are coming from. While waiting for a diagnosis and thus a treatment, I tried all kinds of things to get relief. The truth is that it may or may not help you to take glucosamine. I have heard from many with osteoarthritis that swear it helps, but it did not do anything for me and my forms of arthritis. Do you have other symptoms besides stomach issues and joint pain? Have you had tests to see if this is an autoimmune condition? Have your doctors prescribed anything to treat you? Have you tried heat wraps or topical treatments like biofreeze or stop pain?
