I was prescribed Citro for a ear infection so after 10 days of taking Cipro 500mg 2 times a day, less than 2 days after that I broke out with a fever ranging from 104. - 102.4 for about 3 days at the same time I had joint pain all over my body and pain in my upper legs. On the 4th day after that I broke out in a rash all over my legs and buttocks area, I called the doc that prescribed me Cipro and she said my symptoms had nothing to with the Cipro. I see my dermatologist 5 days after and I find I have a allergic reaction to Cipro. So beware and always get a second, third opinion.
