Exercise your body by tensing and relaxing your muscles, wiggling fingers and toes, and rotating your wrists and ankles to keep them as flexible as possible. If you can't do this, have someone bend and straighten your arms and legs every day to keep you from getting stiff. Lightly powder your sheets or use sheepskin to reduce friction. Someone helping you to reposition can use a sheet to lift you so you don't have to slide on the bed. Try not to elevate the head of your bed more than 30 degrees except at mealtimes.
Pressure ulcers can take a long time to heal if they are completely through the skin.
The rate at which the broken skin heals depends on your general health, diet, and home care. It is best to try to prevent pressure ulcers. If you can move yourself in a chair, shift your weight every 15 minutes. Use soft pillows or sheepskin to keep parts of your body from rubbing together. Try to keep the weight of sheets and blankets off the area with ulcers.
