I have been taking 500mg of cipro for the past two days. I've had light chest pain, on and of body numbness, and a few other odd symptoms. After my period, I kept having the urge to pee even when I went and my uti strip said I had blood in my urine..so my doctor put me on cipro for five days. It seems I'm probably allergic to it and I don't want to take anything else. Would a zpak work for me? I've taken three Benadryls today just to rid of the horrible symptoms. I'm only 18 and pretty fed up with medicines.
