Skin Ulcers
Skin ulcers resemble broken red sores. In advanced cases, the skin area around the ulcers is open and secretes fluid with an unpleasant odor. Skin ulcers are commonly caused by extreme effects such as trauma, exposure to cold or heat, and irritation due to contact with an acidic material.
Skin ulcers are likely caused by lack of blood flow that in turn creates an oxygen-staved environment; which is a breeding ground for infection and bacteria. When a skin ulcer develops the area typically turns dark red or purple and becomes thick, dry and itchy in texture.
