The primary function of the skin, the largest organ of the body, is to protect the body from infections. But sometimes the skin becomes infected when pathogens such as bacteria, virus, or fungus start attacking it. In this article, we will be discussing cellulitis, a bacterial skin infection that develops in the deep layers of the skin.
Cellulitis is a common painful bacterial infection that usually affects the skin of the lower legs, but it can also occur on your face, arms or other parts of the body. The affected skin appears to be red and swollen and is quite painful and warm to the touch.
Cellulitis usually develops on the surface of the skin, but it may also affect the soft tissues underneath and spread to your lymph nodes and bloodstream.
