What should you know about vulvar carbuncle?

A carbuncle is a group of connected, pus-filled boils caused by infection around hair follicles. On the vulva, swelling and tenderness can make sitting, walking, or clothing uncomfortable. Because this skin is sensitive and the infection can extend, a clinician should assess a suspected carbuncle rather than relying on home squeezing.

The lump may feel warm, firm, or fluctuant and the skin around it can become red. Several openings may drain pus. A single abscess, an inflamed cyst, or another vulval condition can look similar, so the diagnosis depends on examination. Diabetes, immune problems, or repeated boils may affect the treatment plan and should be mentioned.

Book a same-day or soon appointment if the swelling is painful or enlarging. Use warm, clean compresses for comfort, wear loose underwear, and wash hands after touching the area. Keep any drainage covered with clean gauze. Do not pierce, cut, or squeeze it. A clinician may prescribe Antibiotics For Skin Infection or recommend Abscess Drainage when trapped pus needs to be released.

Seek urgent care for fever, chills, rapidly spreading redness, severe pain, marked weakness, red streaking, or difficulty urinating. Urgent assessment is also appropriate when the swelling is near the vaginal opening, you are pregnant, or you have diabetes or reduced immunity.

Is this a carbuncle, abscess, or cyst? Does it need drainage? Is an antibiotic appropriate? How should I dress the area, and what can reduce the chance of another boil?
