Hello,
It looks like urinary tract infection or urtehritis to me. Urinary tract (which consists of the kidneys, ureters, bladder, and the urethra) infections are very common in young women. Symptoms of UTI are frequent urination, burning sensation or pain during urination, passing of blood in urine and even fever.
Making a diagnosis of a urinary tract infection includes performing a urinalysis test, which checks for the presence of pus, white blood cells, and bacteria in the urine, which point to a urinary tract infection. A urine culture and sensitivity is usually performed to find the exact microorganism that is causing the infection and to determine the most effective antibiotic to treat it.
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.
