Diaper Rash and Bumps
A diaper rash is a flat, red rash that occurs in the area covered by a diaper. The buttock, upper thighs, lower abdomen (stomach), and genitals are the most common areas affected. It is normally not found within the folds of skin between the body and thighs or body and genitals.
There is variation in what a diaper rash looks like based on how severe it is and what is causing it. In more severe cases, the skin can be painful and the rash raised, thickened, peeling, weeping, and/or bleeding. There may also be blisters, pimples and/or open sores within the red area or on the outside of the main rash.
A yeast diaper rash looks more severe. With this type of diaper rash, bumps or pus-filled blisters may develop around dark red areas of skin. A yeast-infected diaper rash is also often in the skin folds between the body and thighs or around the genitals. The tip of the penis can even be affected.
