Home > Fitness & Health > Health Library > Stages of Pressure Injuries
Pressure injuries (bed sores) are an injury 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 four stages:
In stages 3 and 4 there may be little or no pain due to significant tissue damage. Serious complications, such as infection of the bone (osteomyelitis) or blood (sepsis), can occur if pressure injuries progress.
Sometimes a pressure injury does not fit into one of these stages.
