The clinical symptoms are related to glansitis and syphilis, and need to be diagnosed differently. If the patient has a history of unclean sex, the first thing to consider is the possibility of syphilis, you can promptly go to the hospital to do syphilis antibody test and syphilis serum rapid reaction test to clarify the diagnosis. If the results of these two tests are negative, the possibility of syphilis can be ruled out and the possibility of glansitis needs to be considered. Once diagnosed as glans, you can use potassium permanganate solution for cleaning, then use iodophor for disinfection, you can apply compound polymyxin B ointment for treatment.
