Help. Is it possible to have a diaper rash without the actual rash? My son has been walking wide legged and crying while grabbing at himself all day but when I checked him he doesn’t have any bumps or redness.. slight swelling but that it. I felt around and it seems to be his testies that’s hurting him so I applied some diaper rash cream but it isn’t seeming to help... anyone know what the problem could be.. should I take him to the doctor?
