Cellulitis is a skin infection that can be relatively mild or very serious. It is caused by bacteria that enter the body through an opening in the outer layer of skin, most often in the legs. Symptoms include redness, swelling, heat, and soreness of the affected area.

If the skin around an abrasion on your elbow is inflamed, red, and warm, you may have cellulitis. This is an infection which is caused by bacteria that have invaded the deeper layer of skin through the abrasion. Signs of cellulitis include swelling, redness, warmth, and increased pain in the area.
