I am skaking through my whole body. I've had a sinus infection and was on antibiotics last week and then the shaking started while taking the antibiotics so I finally stopped the antibiotics 3 days ago (on day 8 of 10). I'm still shaking. It starts in the morning and lasts all day. It doesn't go away with eating but feels a lot light low blood sugar. It's hard to concentrate and focus. I also have fribromyalgia and osteoarthritis and am taking Cymbalta (50mg/day) and sulfasalazine (low dose daily).
