Hi there, a few weeks ago I felt as if I had a UTI (I've had several of these before). I took Azithromycin for 5 days but forgot to take the last dose which was 1 pill. The treatment consists of 6 pills. Three days ago I went to the doctor to get a pap smear. Everything went OK with that but when she asked me how I was feeling with urination, I told her I wasn't feeling OK again. She took a urine sample and they found nitrates and bacteria. She sent me Bactrim for 5 days, twice a day. I'm already on my third day about to take my 2nd dose for today and I don't feel too much improvement. Is this normal? I'm really scared.
