Considerations
Pustules are common in acne and folliculitis (inflammation of the hair follicle). They may occur anywhere on the body, but are most commonly seen in these areas:
- Back
- Face
- Over the breastbone
- Shoulders
- Sweaty areas, such as the groin or armpit
Pustules may be a sign of an infection. In some cases, they are non-infectious and associated with inflammation in the skin or taking certain medicines. They should be checked by a health care provider and may need to be tested (cultured) for bacteria or fungus.
