An Introduction to Leg Cellulitis
Leg
cellulitis is a skin infection on the leg that is characterized by swelling, redness, warmth, and pain. It affects people of all ages and can occur anywhere on the body. However, cellulitis mostly affects the legs, feet, arms, and hands. These
types of cellulitis are commonly referred to as "cellulitis of the extremities."
Leg cellulitis is an infection caused by bacteria. The most common cause of this condition in adults with no medical conditions is group A streptococcus, which is a bacterium commonly found in the throat and on the skin.

The most common cause of leg cellulitis in children under the age of three is
