Its hard to know: I see that you have fibromyalgia (FMS). Bad joint pain and fatigue are commonly seen in FMS. Knee twitching is unusual. I suspect it is related to poor sleep and muscle spasm, or possibly anxiety. If not done recently, checking basic electrolytes (calcium, magnesium, sodium) and thyroid function is reasonable. Make sure you see someone that is skilled in treating your FMS symptoms.
