Cellulitis is a bacterial skin infection, which causes inflammation and pain. Unlike other skin conditions like abscesses or rashes, cellulitis affects the deeper layers of the skin and surrounding tissue. Cellulitis can develop anywhere on the body, though it is most commonly found in the legs. It can affect people of all ages and genders, and it should be treated as soon as possible because it can lead to more significant health issues. Obesity, diabetes, poor circulation, and intravenous drug use are all factors that might raise your chances of developing cellulitis.
