Skin abscess

Abscess - skin; Cutaneous abscess; Subcutaneous abscess; MRSA - abscess; Staph infection - abscess

 

A skin abscess is a buildup of pus in or on the skin.

Causes

 

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

 

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

 

Exams and Tests

 

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.

 

Treatment

 

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 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. 

 

Outlook (Prognosis)

 

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

 

Possible Complications

 

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 )

 

When to Contact a Medical Professional

 

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

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

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

 

Prevention

 

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.

    The skin is the largest organ of the body. The skin and its derivatives (hair, nails, sweat and oil glands) make up the integumentary system. One of the main functions of the skin is protection. It protects the body from external factors such as bacteria, chemicals, and temperature. The skin contains secretions that can kill bacteria and the pigment melanin provides a chemical pigment defense against ultraviolet light that can damage skin cells. Another important function of the skin is body temperature regulation. When the skin is exposed to a cold temperature, the blood vessels in the dermis constrict. This allows the blood which is warm, to bypass the skin. The skin then becomes the temperature of the cold it is exposed to. Body heat is conserved since the blood vessels are not diverting heat to the skin anymore. Among its many functions the skin is an incredible organ always protecting the body from external agents.
