Elbow, cellulitis of the: Inflammation of the skin around the elbow due to infection (cellulitis) commonly occurs as a result of abrasions or puncture wounds permitting bacteria on the surface of the skin to invade the deeper layers of the skin. This causes inflamed skin characterized by heat, redness, warmth, and swelling. The most common bacteria that cause cellulitis include Staphylococcus ("Staph") and Streptococcus ("Streop"). One can have an associated low-grade fever. Cellulitis generally requires antibiotic treatment, either orally or intravenously. Heat application can help in the healing process.
