I was given Levaquin for 10days for reacurring sinus infections and ear infections, the same things happened to me my left shoulder started to cramp up real bad. cavles in both legs started to hurt, as well foot pain, and you can not get to sleep no matter what you take. So far I've been awake for 5 days. When I layed down can't close my eyes to sleep they just pop right back open, this goes on all night. The one time I did drift of to sleep, I woke with my heart pounding from a most horrible realistic dream. And another thing I did not know that if you have any type of vessle disease, it may cause a stroke, now why didn't my Doctor tell me this? probably because he did'nt know either.
