What are pressure sores?
Pressure sores are areas of injured skin and tissue. They are usually caused by sitting or lying in one position for too long. This puts pressure on certain areas of the body. The pressure can reduce the blood supply to the skin and the tissues under the skin. When a change in position doesn't occur often enough and the blood supply gets too low, a sore may form. Pressure sores are also called bedsores, pressure ulcers and decubitus ulcers.
What are the symptoms of a pressure sore?
There are 4 stages of pressure sores. Symptoms at each stage include the following:
Stage 1. The affected skin looks red and may feel warm to the touch. The area may also burn, hurt or itch. In people who have dark skin, the pressure sore may have a blue or purple tint.
Stage 2. The affected skin is more damaged in a stage 2 pressure sore, which can result in an open sore that looks like an abrasion or a blister. The skin around the wound may discolored. The area is very painful.
Stage 3. These types of pressure sores usually have a crater-like appearance due to increased damage to the tissue below the skin's surface. This makes the wound deeper.
Stage 4. This is most serious type of pressure sore. The skin and tissue is severely damaged, causing a large wound. Infection can occur at this stage. Muscles, bones, tendons and joints can be affected by stage 4 pressure sores.
Who gets pressure sores?
Anyone who sits or lies in one position for a long time might get pressure sores. You are more likely to get pressure sores if you are paralyzed, use a wheelchair or spend most of your time in bed.
However, even people who are able to walk can develop pressure sores when they must stay in bed because of an illness or an injury. Some chronic diseases, such as diabetes and hardening of the arteries, make it hard for pressure sores to heal because of poor blood circulation.
