I have been on Levaquin for about 4 days now and i have been having a hard time trying to sleep and found myself being restless when trying to relax. I would get mad all of a suden and begin to force my body to move, which in turn caused my muscle weakness to increase. I also am now noticing that since i started this medicine, my testicles have had randome feels of pain as well as when my girlfriend decides to mess around w/ me, i find my self going up and down, incapable of keeping it up as a result. has anyone else had this problem? how long after im off this medicine will this stop?
