I took Cipro for 5 days for a bacterial urinary tract infection and I am so scared of everything I have read and wonder, could it have hurt me? I had some symptoms, back pain or more like a dull ache starting on the 4th day of the Cipro. Sort of a moving feeling in my legs and feet. It was in my stomach and lower abdomen, but moved down to my legs. I do not have any pains at this time, just a funny feeling in my leg and feet, some tingling. My kidneys are working well and my bowels, no problems there. No other symptoms now, they have slowly gone away. Is Cipro really that serious of a drug. I do not take any medications and I am 70 years old, but when I get a urinary tract infection I am forced to take pills.
