A reddened or darkened area of skin appears and does not go away within 30 minutes after you change your position to put less pressure on the area. The skin opens up and may ooze or drain. The ulcer is completely through the skin and may start to involve underlying tissues. Some yellow tissue may be seen. A deep ulcer develops.
Muscle is visible.
Bone may also become visible. Your health care provider will examine your skin. Treatment depends on the severity of the condition. Pressure ulcers need prompt and ongoing care in the early stages to try to avoid tissue damage and infection. Keep pressure off the area.
