I began taking Levaquin, 500 mg @ 1-per-day as an substitute dosage over Amoxicillin after a follow-up visit to my personal physician. I was given the Amoxicillin as part of a regime after a visit to the emergency room the Sunday before with a swollen face due to an outer ear infection--the attending called it: "Swimmer's Ear gone Wild." He prescribed Levaquin, to knock out one ear infection I had contracted the week before (which wasn't healing fast enough) as well as a new infection (middle ear) which began to bother me on Thursday. I am an avid cyclist and felt good and fit enough to participate in a 100 mile bike ride on Sunday. 62 miles into that ride I had to retire due to extreme leg cramps (both legs) of which I had not experienced in my 25+ years of cycling. In fact, it's Tuesday, I'm back at work and the legs are still sore. I know some of you will say I should not have gone riding, but I am physically fit and always ride with a heart monitor to keep my pulse in the proper range. Other side-effects include bouts of anxiety, followed by depression, insommnia, and diarrhea. I will continue to take the meds, but will refrain from riding (except for shorter distances.) until the infection subsides. Thanks
