Pressure sores, also known as pressure ulcers or bed sores, are sores within the skin that cause damage to the skin and underlying tissue. The damage is caused by constant pressure or friction being applied to a part of the body. The extra pressure causes a disruption to the blood flow and without the blood supply, the area becomes starved of oxygen and nutrients. This injury quickly develops for people who have reduced mobility such as wheelchair users or people who are confined to a bed or chair.
If you are a wheelchair user, confined to a bed or chair or have reduced mobility, your risk of getting pressure sores are higher. The areas where pressure ulcers will appear are areas where the body has less fat, so in bony areas like elbows, hip bones, tail bone, shoulder blades, or the back of your arms and legs. Some of the symptoms you should look out for are red, purple or blue torn skin, swelling, parts of the skin that feels warmer/colder than other areas or unusual texture.
