Apse

An abscess is a localized pocket of infection in the body, typically containing pus—a thick fluid made up of dead cells, bacteria, and tissue debris. It forms when the immune system responds to an infection, trapping the infectious material within a cavity surrounded by inflamed tissue. Abscesses can develop in various areas, such as the skin, teeth, or internal organs. They often cause redness, swelling, pain, and sometimes fever. Medical treatment usually involves draining the pus and addressing the infection with antibiotics to promote healing.
