Kotybear, I'm sorry you're so miserable. I don't know where you are in the diagnosis stage. Sometimes that's the hardest part. Doctors are reluctant to prescribe a lot of meds when they don't know what's wrong. A good rheumatologist should be able to help, though. If it's autoimmune-related, like lupus or fibromyalgia, plaquenil is the common choice of drug to help with fatigue and joint pain. It takes a while to really work - sometimes months. But it has very few side affects. I hope your doctors will begin to unravel your health mystery. In the meantime, be sure you get a lot of rest - listen to your body. Avoid stressful situations, eat healthy, exercise a littel (if you can) and stay out of the sun. We're here to listen and to provide information about our own experiences. Sometimes that's helpful. Take care.
