What are the symptoms of a boil?

Boils exhibit multiple symptoms, including the formation of rigid, sensitive, swollen, bright red areas in the skin. Boils become more painful and less rigid as they develop. Typically, a boil should clear up in two weeks or less. If you have a boil that lasts for more than two weeks, contact your health care professional.

Common symptoms of boils

You may notice symptoms of boils daily or just once in a while. At times, any of these symptoms can be severe:

  • Fever not associated with flu symptoms
  • Fluid leakage from the boil, which may crust over
  • Itching feeling
  • Rigid, sensitive reddened area of skin ranging in size from a few millimeters to several centimeters
  • White or yellow centers in the boil (pustule)

Symptoms that might indicate a serious condition

In some cases, boils can be a serious condition that should be evaluated by a health care professional. Seek prompt medical care if you, or someone you are with, have any of these serious symptoms including:

  • Boils located in the middle of the face or on the spine
  • Boils that last longer than two weeks
  • Fever not associated with flu symptoms
  • Recurrent boils

Boils are very common and may be caused, in part, by conditions that weaken the immune system, thus increasing an individual’s susceptibility to infection, or by poor hygiene....

TREATMENTS

How is a boil treated?

Boils should heal on their own after several weeks, but will only do so after they are opened and drained.
