my 9 month old has had his testicles red for about almost two weeks. when i first saw it i put rash cream,for about three days, it dint go away so i change diapers because i thought that he might be allergic to the brand of diapers,it dint help i bought another rash cream thats for severe rashes dint help,put vaseline dint help, im not sure what else to do he scratches alot cause it itches. so what can i do? whats wrong? is there something else i cant do so it will go away?
