If you have a slight stinging pain in your urethra when you urinate, you may have a non-gonococcal urethritis caused by an unclean sexual contact with mycoplasma or chlamydia, or you may have a urinary tract infection caused by a common bacterial infection due to a low resistance. It is best to choose medication after further examination, including urine routine and culture of urethral secretions to clarify the specific pathogenic microorganisms. If it is only a common bacterial infection causing urinary tract inflammation, you can choose to take Sanjin tablets, Feverfew capsules, Bazheng capsules, levofloxacin tablets, cefuroxime tablets orally for 3-5 days to get effective relief of symptoms. If it is clear through examination that the UTI is caused by mycoplasma or chlamydia infection, you need to choose azithromycin tablets, memantin capsules, doxycycline capsules for 2-3 weeks of continuous treatment to clear mycoplasma and chlamydia, and the symptoms can be completely well.
