Abscess

An abscess is an infection characterized by a collection of pus under the skin. Bacteria commonly causing abscesses are Staphylococcus aureus (commonly known as “staph”) and Streptococcus (commonly known as “strep”). These bacteria enter the skin through any cracks or injury to the skin. The area of skin then becomes tender, warm, and swollen over days to 1-2 weeks, and a fever may develop. Abscesses can sometimes form if minor superficial skin infections are not treated appropriately and in a timely fashion. Most abscesses resolve quickly once appropriately treated.



Who's At Risk?

Abscesses can occur in anyone.

Factors that predispose individuals to developing an abscess include:

  • Any skin infection, especially those that are untreated.
  • Diabetes.
  • Obesity.
  • A weakened immune system due to underlying illness or medication.

Signs & Symptoms

A worsening tender swelling that arises over a period of 1-2 weeks. In lighter skin colors, abscesses may appear red or purple, and in darker skin colors, they may appear purple or brown. The pus underneath the skin is usually not visible, but you may be able to feel fluid in the abscess when you press on it. The child may have a fever or may generally feel unwell.

Self-Care Guidelines

There are no self-care options for abscesses. While waiting to see your child’s medical professional, you can try applying a warm compress to the affected area and giving the child ibuprofen (eg, Advil, Motrin) to help with the swelling and pain.

To prevent the spread of infection to others, infected wounds, hands, and other exposed body areas should be kept clean and wounds should be covered until healed.

Treatments

Your child’s medical professional may drain the pus or fluid collection by making a small incision in the skin after it has been numbed. This will drain most of the bacteria, helping the body fight the small amount of bacteria that remains. This fluid may then be sent to a laboratory for testing (a bacterial culture). The culture can determine what type of bacterium is causing the infection and also what antibiotics will work best to treat it. The medical professional may choose to have your child start oral antibiotics aimed at treating the most common bacteria that cause abscesses. However, if the infection is small and it has been drained, they may decide not to treat with oral antibiotics.

If your child’s symptoms are not improving or it is determined that the bacterium is not one of the common types, your child’s medical professional may prescribe different antibiotics. If antibiotics are prescribed, it is important for the child to take the entire course as prescribed, even if they are feeling better or the infection appears to be gone after just a few days. If your child has been taking antibiotics and the infection does not improve or they are still feeling unwell after about 2-3 days, return to see their medical professional.

Visit Urgency

A worsening tender, swelling area should prompt you to make an appointment with your child’s medical professional as soon as possible. If the area involves the child’s face, spreads very rapidly, or is in an area that severely limits their functionality, you should seek emergency care for the child.
