Cellulitis is a common, potentially serious bacterial skin infection. Cellulitis appears as a swollen, red area of skin that feels hot and tender. It can spread rapidly to other parts of the body.
Skin on lower legs is most commonly affected, though cellulitis can occur anywhere on your body or face. Cellulitis might affect only your skin’s surface. Or it might also affect tissues underlying your skin and can spread to your lymph nodes and bloodstream.
Left untreated, the spreading infection can rapidly turn life-threatening. It’s important to seek immediate medical attention if cellulitis symptoms occur.
Cellulitis occurs when bacteria, most commonly streptococcus and staphylococcus, enter through a crack or break in your skin. The incidence of a more serious staphylococcus infection called methicillin-resistant Staphylococcus aureus (MRSA) is increasing.
Although cellulitis can occur anywhere on your body, the most common location is the lower leg. Bacteria is most likely to enter disrupted areas of skin, such as where you’ve had recent surgery, cuts, puncture wounds, an ulcer, athlete’s foot or dermatitis.
