A tingling and pus flowing from the urethra is a sure sign that you have a urinary tract infection. It is important to note whether there is frequent urination and whether there is a history of unclean sexual intercourse. This situation must be tested for urine routine, take the retained pus for bacterial culture, at the same time should pay attention to exclude whether there are sexually transmitted diseases. The pus should be taken to find if there is gonococcal, mycoplasma, or chlamydia infection. If it is a common infection, oral broad-spectrum antibacterial agents will improve significantly in 2-3 days. If the test finds gonococcus, this is gonorrhea, and a high dose of penicillin or ceftriaxone sodium, administered intravenously, will be used to achieve a cure in 3 days. If there is mycoplasma or chlamydia infection, it is treated with oral roxithromycin or doxycycline, which requires 7-10 days of treatment.
