I also have ostearthritis in my back and knees. I take glucosamine sulfate for my knees and I take a lot of calcium every day - 2 600 pills with Vitamin D 400 and I eat a lot of dairy foods. How can I tell if my pains in the back are from osteoarthris or from collapsed vertabraes in the back. I had four collapsed vertabraes in my back in February and I thought that they healed. Now I'm getting pains in my back, shoulders and arms and neck. Is it fractures or arthritis?
