Cellulitis is a condition in which the superficial layer of skin and underlying tissue gets infected. The same cellulitis when affecting the soft pad of fingertip is termed as felon. Generally, a felon does not affect deeper structures of the finger and hand but infects fingertip pad and soft tissues connected with it which often occurs due to a punctured wound. The fingertip is supported with walls of connective tissue, which steady the pad. There is entrapment of pus in these compartments with infection provoking extreme discomfort and throbbing pain. There is swelling, heat and redness. Pus accumulation may also be visible.
