What should you know about worst carbuncle?

A carbuncle is a cluster of linked boils, usually caused by infection around hair follicles. It may feel hot, firm and tender, with several points that drain pus. More extensive inflammation can make the surrounding skin red and swollen, and the area may limit movement if it is near a joint.

Do not squeeze, pierce or cut it at home. Pressure can push infection deeper or spread bacteria to nearby skin. A clinician can decide whether you need antibiotics for a skin infection or whether an abscess needs drainage.

Keep the area clean and covered with a fresh dressing if it is draining. Wash your hands before and after touching the dressing, avoid sharing towels, and launder clothing or bedding that contacts the fluid. A warm, clean compress may ease discomfort, but stop if it increases pain or redness.

Arrange a clinical review if the lump is large, recurrent, very painful, or not settling. Treatment may include [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/) or [Abscess Drainage](/treatments/minor-procedures/abscess-drainage/), depending on what is found.

Seek urgent medical help for rapidly spreading redness, red lines moving away from the lump, severe or escalating pain, fever, chills, confusion, marked weakness, or swelling near the eye. Seek prompt care as well if you have diabetes, reduced immunity, or repeated boils, because infection may need closer assessment.

Ask whether the lesion needs drainage, whether a swab is useful, how to dress it safely, and how to reduce spread to household contacts. Mention previous boils, recent medicines and any condition that affects healing.
