I have had 4 uti's in 2 months. cultures came back normal and it seems to not be responding to a variety of antibiotics. what can i do?

Sounds like: Your problem isn't infectious. You will need an evaluation for the other causes of bladder irritation, and this would be best done by a urogynecologist. You should be sure to be tested for sexually transmitted infection if you are sexually active, and most likely you will need a pelvic ultrasound and cystoscopy. There are medications and lifestyle changes that can help as well. Call MD 4 referral.
