They are a skin disease and in most cases are not due to anything wrong with the blood. Another name for a boil is a furuncle, and when multiple boils occur on the body, the condition is called furunculosis. Several boils joined together with tunnels under the skin are called a carbuncle. Boils are caused by a hair follicle (a tiny tunnel in the skin where hair grows from) or a tiny cut or scratch becoming infected by a bacteria (usually Staphylococcus aureus). As a boil gets larger it gets a cavity inside it filled with pus. As a boil starts to develop, the body's immune system carries white cells in the blood to the site of the boil to do battle with the invading bacteria. The body also creates a fibrous wall around the 'battleground" to contain the infection. Once the boil reaches a certain size, this fibrous wall prevents antibiotics in the bloodstream penetrating into the boil. Dead white cells and dead bacteria make up the liquid pus in the center of the boil and, because this liquid forms under pressure, it becomes painful. Bacteria can cause different types of skin infections. Three common skin infections that you and your doctor may encounter are: (1) cellulitis, (2) folliculitis, and (3) impetigo. Keep in mind that skin infections vary in presentation and treatment. Therefore, it is important to talk to your doctor to obtain an appropriate diagnosis and treatment plan. You may experience pain, swelling, tenderness, warmth, and redness in the infected area. If you have a severe case of cellulitis, you may experience fever, tiredness, and a lowering of blood pressure. If left untreated, pus may form and cells may die in the infected skin area. Cellulitis can involve any part of the body but most often affects the leg.
