My daughter was diagnosed with Chlamydia in early June. She took Azithromicin and was retested 4 weeks later. Her boyfriend came back negative but she came back equivicable. She took another round of Azithromiacin and about three weeks later was still having a burning sensation in her bladder. She was tested for a UTI which was negative and took one round of Doxycyclene. That sensation had started to diminish at the end of the doxy treatment but 7 days later is starting to come back again. She was tested for all other STDs and all came back negative. She has not been with that boyfriend or anyone else since the second round of Azithromiacin. Should I take her to a urologist. Do you think that she has some persistent chlamydia or some sort of cystitis in her bladder. She is scheduled to have the test of cure on Sept 21. It is possible that it is resisting all antibiotics?
