Symptoms

In cellulitis, the affected skin feels warm and is usually red, swollen and painful. The redness can be slight or can stand out compared to surrounding skin. The area of warmth can be felt with the back of the hand, especially when compared to surrounding skin. There may be a spreading network of red streaks in the skin, caused by infection in the vessels that carry lymph (tissue fluid), as well as enlarged lymph nodes (swollen glands) near the area of infection.

Fever and a general sick feeling (malaise) often accompany cellulitis. Severe infections can cause low blood pressure if bacteria get into the bloodstream. Bloodstream infections (blood poisoning) from cellulitis are particularly dangerous in the very young and very old, as well as in those with weakened immune systems or abnormal heart valves.
