A boil is a red, swollen, painful bump under the skin. It often looks like an overgrown pimple. Boils are often caused by infected hair follicles. Bacteria from the infection form an abscess, or pocket of pus. A boil can become large and cause severe pain. Boils most often happen where there is hair and rubbing.
Boils begin as a red swollen area of the skin and develop into a larger, pus-filled pustule. The area may itch in the beginning and become more painful as the boil fills with pus. Pustules may form and appear with a white or yellow center. Boils are usually pea-sized but can be as large as a golf ball, usually growing at a rapid pace. Fatigue and fever may accompany the boil. The surrounding skin is red and swollen. Treatment. Treatment of boils should be directed by a health-care provider.
