I was told I had a sinus infection and given Levaquin-550mg and was to take them for ten days. The first day I became ill from a nausea attack. I took some tagament and got some relief. In the AM I woke up with hand pain. I took the pill again for the second time and about two hours later I began sufferring from nausea and chills..After reading the posts involving this drug I am getting off ASAP and hoping for the best. Thanks for taking the time and putting your individual incidents on line..
