Bedsore; Decubitus ulcer
A pressure ulcer is an area of skin that breaks down when constant pressure is placed against the skin.
Pressure against the skin reduces blood supply to that area, and the affected tissue dies. This may happen when you stay in one position for too long without shifting your weight. You might get a pressure ulcer if you use a wheelchair or are confined to a bed, even for a short period of time (for example, after surgery or an injury).
