Pain during urination without discharge is generally not gonorrhea; clinically, it is more commonly a urinary tract infection, such as cystitis. Patients with cystitis, due to the inflammation irritating the bladder mucosa, generally exhibit signs of bladder irritation, characterized by frequent urination, urgency, and painful urination. The pain during urination is usually felt as a stabbing or burning sensation in the urethra, but those with cystitis generally do not have any discharge. Clinically, to confirm whether it is gonorrhea, one must first consider the patient's medical history, since gonorrhea is a sexually transmitted disease. Typically, there is a history of unprotected sexual activity before the onset of symptoms, which primarily include redness and swelling of the urethral mucosa, discomfort and itching in the urethra, and painful urination. There would also be a significant amount of white discharge from the urethral opening, consisting of pus. Therefore, the absence of discharge generally rules out gonorrhea. A urine culture can also be done to determine the type of bacterial infection.
