Yes. The combination of glucosamine and chondroitin has been shown in studies to (1) provide a degree of pain relief in the short term, and (2) trigger growth of new cartilage when taken for at least two years straight. So it can help you pain and reverse some of the chronic damage. You can find this in the health food store.
See a rheumatologist. You will get better result from real therapy. Why waste your investment in "alternative"? You are better off in the real world rather in fantasies promoted by fast talking con men.
