About Pressure Sores

Pressure sores are areas of damaged skin caused by staying in one position for too long. They commonly form where your bones are close to your skin, such as your ankles, back, elbows, heels and hips. You are at risk if you are bedridden, use a wheelchair, or are unable to change your position. Pressure sores can cause serious infections, some of which are life-threatening. They can be a problem for people in nursing homes.

You can prevent the sores by :

  • Keeping skin clean and dry
  • Changing position every two hours
  • Using pillows and products that relieve pressure

Pressure sores have a variety of treatments. Advanced sores are slow to heal, so early treatment is best.

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.

Research on Pressure Sores

586 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.

What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
