Beens symptoms and conditions

1st day with Levaquin 500 mg,di exactly what the medicine said, eat and drink lots of liquid... approx 4 hrs after taking it for sinus infection on my way to work: extreme nausea, profuse sweating all over, felt like I was going to throw up or pass out while driving. My whole body tingling with sharp needle burning pains...drove myself right to ER at Hospital. About 30 minutes later, exhausted, withchest wall pains. Had and EKG but all was well. Have not really slept yet and it beens 24 hrs since I took it. Still feel weak but I have to go to work.
