Hello dear I understand your concern Severe pain could be due to urinary tract infection and stone in the urethra/bladder. I would suggest to consult the urologist/gynecologist and undergo urine routine and microscopic, and USG scan to rule out the above cause. Doctor will give following advises: Tablet septran DS Tablet nitrozolium and pyridium Syrup cital Drink plenty of water and fruit juice of the cranberry, orange and pineapple Maintain proper pelvic hygiene by using v vaginal plus wash Maintain proper hygiene before and after sex Hope this may help you Contact HMC for further health query Best regards Dr. Sagar
