What Causes Blood In Urine With Painful Urination?
interstitial cystitis
Detailed Answer:
Thank you for contacting HCM with your health care concerns
I am sorry to hear that you are experiencing pain with urination and blood in your urine. Since the antibiotics did not help you may have interstitial cystitis. This is a disease of unknown cause that creates difficulty urinating with blood. The diagnosis is made by a cystoscopy where they look inside your bladder and see inflammation. There are treatments but they need to be done by a urologist. I recommend that you see your medical provider again for a referral to a urologist. The urologist will be better qualified to make a diagnosis.
I hope I answered your question. Please contact us again if you have any additional questions
