Skin abscesses are common and affect people of all ages. They occur when an infection causes pus to collect in the skin.

Skin abscesses may occur after developing:

• A bacterial infection (often staphylococcus)
• A minor wound or injury
• Boils
• Folliculitis (infection in a hair follicle)

A skin abscess may occur anywhere on the body.

Symptoms may include:

• Fever or chills, in some cases
• Local swelling around the infected spot
• Hardened skin tissue
• Skin lesion that may be an open or closed sore or a raised area
• Redness, tenderness, and warmth in the area
• Fluid or pus drainage

Your health care provider can diagnose the problem by looking at the affected area. The drainage from the sore may be sent to the lab for a culture. This can help identify the cause of the infection.

You can apply moist heat (such as warm compresses) to help the abscess drain and heal faster. Do not push and squeeze on the abscess.

Your provider may cut open the abscess and drain it. If this is done:

• Numbing medicine will be put on or into your skin.
• Packing material may be left in the wound to help it heal.

You may need to take antibiotics by mouth to control the infection.

If you have methicillin-resistant Staphylococcus aureus (MRSA) or another staph infection, follow instructions for self-care at home.

Most skin abscesses can be cured with proper treatment. Infections caused by MRSA respond to specific antibiotics.

Complications that can occur from an abscess include:

• Spread of the infection in the same area
• Spread of the infection into the blood and throughout the body
• Tissue death (gangrene)

Contact your provider if you have any signs of skin infection, including:

• Drainage of any kind
• Fever
• Pain
• Redness
• Swelling

Contact your provider right away if you develop new symptoms during or after treatment of a skin abscess.

Keep the skin around minor wounds clean and dry to prevent infection. Call your provider if you notice signs of infection. Take care of minor infections promptly.
