Cellulitis is a skin condition that is both fairly common and could become increasingly serious. The skin area that falls under the infection reddens and swells up. This area is also usually painful to touch and is warmer than others.
Typically the main target areas are the lower legs. However, it could also show up on the face and arms as well as on other body parts. The main cause for its occurrence is the entry of bacteria through a crack in the skin.
If this infection is not treated timely, it could become deadly. Once it spreads to the bloodstream it might even prove fatal. However, one good thing is that this infection cannot be transmitted from one to the other.
