hhahaha..this is the best way to get rid of them ballz entirelyDO NOT! and I repeat. DO NOT PUT CREAMS LIKE DEEP HEAT EVEN NEAR YOUR BALLS¡ or anywhere near the scrotum area.
3days is a long time, you should shower at least daily, depending on how much you sweat. Anyways that is supposed to be a precaution, now you have whatever you have and I suggest you do see a doctor, because we can't be sure what you really have. Also if it is something fungal or bacterial take it seriously if you won't treat it properly it will not go away just keep on recurring.
but anyways...STD to ni?
