Abscess is a soft mass of tissue with pus (collection of bacteria and dead cells) formed inside. Abscess usually remains warm and causes pain. It develops most commonly in the armpits, near the genitals or in the back. The inception of abscess occurs when there is an obstruction in sweat glands, infection in body hair follicles or slight rupture in skin. This allows the bacteria to penetrate the skin or into the glands. This in turn activates the body’s defense system to kick off these microbes. Thus initiates an inflammatory response by the body, which is depicted as abscess. In persons who have a weak immune system, abscesses crop up more, than someone with an excellent immunity.
