I keep on having frequent UTI s, I m 65, at least 3 times a year.. The dr. put me on cipro and it didn t clear up, so I m suppose to start cipro again. probably tomorrow. Problem is I never have any symptoms of UTI, no burning. I also have psoriasis. What should I do if it doesn t clear up again, and is there anything I can take all the time to prevent these UTI s from reoccurring?
