I am having small and large joint pain (fingers in particular, both hands, hip joints, big toe joint, back and shoulder pain), I'm almost 60 (in Dec.), and feel exhausted all the time, worse by late afternoon. I take multi-vitamins and extra calcium with Vit. D, HRT and Vytorin 10/20. Have had back problems for years (bulging disk), but getting worse. Don't sleep well, wake up with fingers hurting, legs ache, tired. What tests are best to identify problem or problems? Could it be fibromyalgia (I've had a lot of stress in my lifetime!) and some form of arthritis, or something else? What type of specialist should I see to diagnose the problem?
