Abscess

Skin Abscess (Boil)

Overview

A skin abscess is a localized collection of pus within the skin and subcutaneous tissue, typically caused by bacterial infection, most commonly Staphylococcus aureus. It forms when bacteria enter through a break in the skin, leading to inflammation, tissue destruction, and an enclosed pocket of pus. Abscesses are painful and often require drainage.

Key Symptoms

• Firm, tender, fluctuant swelling under the skin
• Red, warm, and painful to the touch
• May develop a visible white or yellow point (head)
• Surrounding skin often red and swollen (cellulitis)
• May cause fever if large or deep
• Pain increases as the abscess enlarges with pressure buildup

Affected Areas

Axillae (armpits), Groin, Buttocks, Face, Any area of skin

Care Instructions

1. See a healthcare provider for evaluation — most abscesses require incision and drainage.
2. Do not attempt to squeeze or lance an abscess at home.
3. Apply warm compresses to promote drainage and relieve pain.
4. Take prescribed antibiotics if recommended by your provider.
5. Keep the area clean and change dressings as instructed after drainage.
6. Return promptly if the area worsens, spreads, or you develop fever.
