Pressure sore, or bedsore, on the back of a 65 year old woman. Pressure sores (decubitus ulcers) occur on people who are immobilised or bedridden. Constant pressure on an area of skin causes it to break down, leading to infection. Infected sores enlarge and deepen over time. Treatment is with antibiotic drugs and dressings, although large sores such as this may take a very long time to heal. Prevention of pressure sores is easier than curing them. Frequent turning and scrupulous hygiene help to prevent the formation of pressure sores in bedridden people.
