L03.0: Cellulitis of finger and toe

Cellulitis of the finger and toe is a bacterial infection that involves the skin and underlying tissues of the finger or toe. Typically caused by common bacteria like Streptococcus or Staphylococcus, the condition usually begins as a small area of redness, pain, and swelling on the skin. It often arises after a break in the skin due to a cut, scratch, or insect bite, although sometimes it may occur without an obvious source of infection. As the condition progresses, the infection can spread, causing the red and swollen area to grow larger and potentially affect the entire digit. Further, symptoms like fever, chills, or swollen lymph nodes may develop if the infection spreads to other parts of the body. Without proper treatment, cellulitis can become a severe health risk.
