This January my son (2 years old) got a rash in the pelvic area that became infected, having a white top on each spot. He was prescribed mupirocin and he got well. The rash came back, also in his legs (like spreading) Everytime he has the rash (looks like pimples 5-6 at the time in the pelvic area and his penis very swallen and red) The rash came back for the 3rd time and the doctor said that was yeast, now he was prescribed nystatin, got better. Now for the 4th time, it came back, I put immediatly the mupirocin, but this time the rash persisted and I was told to put also the nystatin, the rash is going away, but not the redness in the penis and he screams everytime we change his diaper and complains about pain all day and all night. I don't think this is a yeast infection anymore, i feel he has a virus in his system or maybe something related to the penis that makes him scream. Please advise me!
