A pressure injury on the skin is caused by constant pressure to that area. The pressure damages the skin and underlying tissues, creating an injury. This can happen when you lie in bed or sit in a wheelchair for a long time. And it can happen much more quickly when the health of your skin is affected by problems like poor nutrition or a disease that affects your blood circulation.
Pressure injuries usually occur over bony areas, such as your sit bones, hips, lower back, elbows, heels, and shoulders. They also can occur in places where the skin folds over on itself. You may have mild redness or open wounds that are harder to heal.
Good care at home can help heal pressure injuries. This includes keeping pressure off the area and following your doctor's instructions on caring for your injury. Eating a healthy diet with enough protein can also help with healing.
A pressure injury (pressure ulcer) is caused by constant pressure to an area of skin. The pressure damages the skin and underlying tissue, creating an injury.
This often occurs when a person lies in bed or sits in a wheelchair for a long time. Pressure injuries usually form over bony areas such as your sit bones, hips, lower back, elbows, and heels. To prevent pressure injuries, you need to change positions often.
Severe pressure injuries are hard to treat and slow to heal. If they don't heal, they can lead to skin, blood, or bone infections.
Pressure injuries develop when constant pressure on an area of skin damages the skin and underlying tissues, creating an injury. Pressure injuries can range from mild reddening of the skin (early stage) to severe tissue damage that extends through the skin and soft tissue and into the bone (late stage).
At first, the skin may appear reddened. Or the skin may look purple or dark red. In darker skin, the color may differ from that of nearby skin. The injury may be tender and warm to the touch. It may break open or form an ulcer where fat, bone, or muscle may be visible.
Treatment focuses on helping the pressure injury heal. This involves keeping pressure off the area. Injuries with unbroken skin may need to be kept clean and bandaged. For open injuries, your doctor may remove dead tissue from the wound to prevent an infection. You may need special dressings. Some people may need surgery.
Relieving and spreading out pressure is the most important part of both preventing and treating pressure injuries. Putting pressure on one spot for long periods of time damages the skin and underlying tissues. Pressure can be relieved and spread in several ways. Often a combination of these is best.
If you or someone you care for is not able to move much, it's important to prevent pressure injuries and to check the skin every day. If you think that a pressure injury is forming, take steps to treat it. Talk to your doctor or nurse about what more you can do.
A doctor can diagnose a pressure injury by examining it. In some cases, the doctor may want to do blood tests to check for infection or to see if you're getting enough protein in your diet. The doctor may also want to do a skin and wound culture or a skin biopsy.
Pressure injuries are caused by constant pressure on the skin. They often form on skin that covers bony areas. Common sites include the back of the head and ears, the shoulders, the elbows, the lower back and buttocks, the sit bones, the hips, the inner knees, and the heels.
Pressure injuries may also form in places where the skin folds over itself. And they can occur where medical equipment puts pressure on the skin. For example, they may form where oxygen tubing presses on the ears or cheeks.

Pressure injuries can range from red areas on the surface of the skin to severe tissue damage that goes deep into muscle and bone. Severe injuries are hard to treat and slow to heal. When pressure injuries do not heal properly, problems such as bone, blood, and skin infections can develop.

Other things that can make pressure injuries more likely include:
Pressure injuries are injuries to the skin and underlying tissue. They can range from mild reddening of the skin to severe tissue damage—and sometimes infection—that extends into muscle and bone. Pressure injuries are described in the following stages.
Serious complications, such as infection of the bone (osteomyelitis) or blood (sepsis), can occur if pressure injuries progress.
