An abscess is a pocket of pus that can form almost anywhere in or on your body. It is caused by a bacterial infection, usually by a bacteria called Staphylococcus. When bacteria enter your body, your immune system sends white blood cells to fight the infection. This process causes inflammation, and the tissue nearby dies. When this happens, a pocket forms and fills with pus, creating an abscess.

Symptoms of an abscess include:

• A tender mass that is often surrounded by a colored area from pink to deep red.
• Pain, swelling, and warmth in the affected area.
• Fever and chills.
• Fatigue, excessive sweating, loss of appetite or weight.

A very small abscess or one close to the surface of your skin may resolve by itself. You may be able to get rid of an abscess by applying a warm compress to the area. It may drain naturally, but you shouldn’t attempt to drain or burst an abscess at home. If you try to squeeze the pus out of an abscess yourself, it can easily spread the bacteria to other areas of your skin. Treatment for an abscess typically involves drainage and antibiotics. You should receive treatment if the abscess persists longer than 2-3 days to prevent its rupture spreading and infection. You should see the doctor immediately if you develop a fever and increased pain.
