An abscess is a localized collection of pus that forms within the body due to infection, inflammation, or blockage. It typically occurs when the body's immune system responds to bacteria or foreign substances, leading to the accumulation of white blood cells, dead tissue, and bacteria. Abscesses can develop in various parts of the body, including the skin, teeth, and internal organs. Common symptoms of an abscess include swelling, redness, pain, and warmth in the affected area. In some cases, abscesses may require medical treatment, such as drainage or antibiotics, to eliminate the infection and promote healing. Proper hygiene and prompt medical attention can help prevent complications associated with abscesses.
