I was married for 43 years and in a monogamous relationship until my husband passed away from cancer 2 years ago. In June I began an intimate relationship with a divorced man who had been celibate for 5 years. I have MS, an autoimmune disease. I have been fighting a UTI since June and have been on Macrobid, which did not work. I was the prescribed Ciproflaxin (spelling ?) which appeared to work, but needed to be put back on it 2 weeks later. I now have another infection which I believe is also a UTI. What is the best antibiotic for me to get rid of this? I have not had UTI’s until June of this year.
