Hi, I started having pain with sex about 4 days ago and then pain with urination (esp towards the end of emptying my bladder), urgency even after emptying the bladder, and low belly pain, & blood in my urine 3 days ago. I called my doctor and he called in 3 days of cipro and pyridium for UTI. I am now finishing day 3 and I have been drinking copius amounts of water and cranberry juice. I still have pain at the end of clearing my bladder, low belly pain, and urgency and feeling that I always have to pee. My blood has subsided. Should I get a different antibiotic?
