You really have your hands full! I have had RA, fibromyalgia, OA and Sjogren's for 34 years, none of which showed up on tests until the past two years. I have been on the drugs you named. At one time I was on Hydrocodone for 15 years. I didn't get addicted because I only took it when pain was unbearable (a 7 or up), so rarely daily use. I have family members with bipolar, as well, and my suggestion would be to see a therapist, both for support with bipolar and for help in dealing with the other things on your plate. It is very easy to get overwhelmed dealing with all that you are. I agree that a rheumatologist is far better trained and better able to diagnose. I also use progressive relaxation, both to keep the pain down and to sleep. I also have changed my diet to a Mediterranean diet, with emphasis on anti-inflammatory foods. I use pool exercises, which I got from PT. I have consulted with an OT, as well, to learn how to do things in a way that produces less pain and makes long term mobility possible. Sometimes tens units help, as do ice packs or heat packs, depending on what works for you. Our diseases are not things that can be easily treated and it often takes a team approach to get it right. Above all else, I listen to my body and when it says "Stop", I do. I can't say that I like stopping, because I don't, but it is better than the pain I will suffer and the long-term damage I may do by continuing. Please stay in touch and keep us updated. Be good to yourself, this is the only body you are going to get!
