Hello,
Pain after urination can be due to urinary tract infection. To diagnose a UTI please get a complete urine examination and urine culture done. The other causes are prostatitis in males, vaginitis in females and STD’s.
Complete profile of investigations are needed to confirm a diagnosis for which I suggest you to consult a urologist,
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
have you been tested for an UTI? If not then I would do so, because it sounds exactly like you have one, which will require antiboitics. Don't continue to do nothing, because it could go to your kidneys which is bad.
