I too had symptoms similar to yours. All kinds of tests, etc. two years ago conclusion was: fibromyalgia which basically is a chronic sleep disorder...not getting enough deep restorative sleep. It gives people all kinds of symptoms. Relieving stress and learning to live with it and finding right medications for YOU and Drs. who will be supportive really helps. Best help is Arthritus Foundation they have free self-help classes on fibro and support groups etc. Might consider looking into that and joining good support group. Good luck and prayers.
