I have burning sensation after urination. No problem. In urinating i. Was diagnosed with. Mild cystitis and was prescribed a 21 day antibiotic course. I went off. But from yesterday I started feeling the burning sensation. Doctor advised me before that if it continues he may have to do a cystoscopy. In case it comes back. He advised the passage in urethra may have shrunk because of which i Can not empty My Bladder properly And.The remaining urine Left in Bladder and urethra creates burning sensation. Please advise the further plan Of action.
