What should you know about boil and carbuncle treatment?

A boil is a painful infection centred on a hair follicle. A carbuncle is a connected cluster of boils, often with more than one opening and a wider area of inflammation. Both can cause warmth, tenderness, swelling and pus. They may occur on areas affected by friction or sweating, and a carbuncle can make you feel generally unwell. Do not squeeze, pierce or cut either lesion because this can push infection deeper or spread it to nearby skin.

Apply a clean warm, moist compress for short periods several times through the day, wash your hands before and after touching the area, and cover drainage with a clean dressing. Do not share towels, razors or clothing, and wash used fabrics regularly. A clinician may recommend Abscess Drainage when pus is trapped, or Antibiotics For Skin Infection when infection is spreading or the person has higher medical risk. Take prescribed medicine exactly as directed and attend review if the wound is not improving.

Get prompt medical advice for a carbuncle, a lesion on the face or near the eye, rapidly expanding redness, red streaks, severe pain, fever, chills, or repeated boils. Seek earlier assessment if you have diabetes, a weakened immune system or medicines that suppress immunity. Emergency help is needed for confusion, collapse or trouble breathing.

Ask whether the lesion needs drainage, whether a swab is useful, which dressing to use, how to reduce spread at home, and what symptoms should trigger urgent reassessment. If boils recur, ask about possible sources and prevention steps.
