What is some background information about Pustules?

  • Back
  • Face
  • Over the breastbone
  • Shoulders

Pustules may be a sign of an infection. In some cases, they are non-infectious and associated with inflammation in the skin or medicines. They should be checked by a health care provider and may need to be tested (cultured) for bacteria or fungus.
