What Are Pressure Sores? (Pressure Ulcers)
Pressure sores (pressure ulcers or bed sores) happen when pressure on your skin cuts off your blood supply. This usually happens in areas where your bones are closer to the surface (bony prominences). This makes your skin and the tissue below your skin break down. Pressure sores often happen if you lie or sit in one position for too long. They can be painful and heal slowly. But you can do many things to help stop pressure sores.

Where pressure sores occur
Pressure sores form where bone presses your skin against a bed or chair. This is most likely to happen in places where there is less padding between the skin and the bone. This includes your head and feet, and around joints like your shoulder, hip, and knee.

Cracked, blistered, or broken skin
