I've had burning sensation and frequency about 4 months now. It started the morning after intercourse. All std and bacteria seeking tests have come back negative and the urologist has given me sample medications to try that my Grandmother is even on. I'm his youngest patient by at least 30 years. He suggests IC but i dont experience any pain, just burning around urethral opening and vaginal area when i feel the urge to pee, during urination, as well as about 10 minutes after. I'm at a loss and would like a better diagnoses so I can make myself knowledgable on how to treat it. Thanks for your input.
