I have been prescribed Levaquin and Bactrim and they both make me feel so very shaky... I feel like I am just trembling and anxious. It is a terrible feeling! I need to get this taken care of and am afraid to try other antibiotics. I need to know of other drugs that don't cause this side effect! I also have a kidney stone I am trying to pass right now and dealing with the two things at once is not a good time!!
