About this information

This NHS content is written for people in England. Services, entitlements and contact routes may differ in other countries.

Symptoms of a pressure ulcer

Pressure ulcers usually form on bony parts of the body, such as the heels, elbows, hips and tailbone.

Symptoms of a pressure ulcer include:

  • discoloured patches of skin that do not change colour when pressed – the patches are usually red on white skin, or purple or blue on black or brown skin
  • a patch of skin that feels warm, spongy or hard
  • pain or itchiness in the affected area of skin

The ulcers usually develop gradually, but can sometimes appear over a few hours.

They can become a blister or open wound. If left untreated, they can get worse and eventually reach deeper layers of skin or muscle and bone.

See a GP if:

  • you think you or someone you care for have a pressure ulcer

Ask for an urgent GP appointment or get help from NHS 111 if:

You or someone you care for have symptoms of a pressure ulcer and:

  • hot, swollen or red skin – it can look blue or purple on brown or black skin
  • pus coming out of the ulcer
  • a high temperature
  • severe pain or pain that's getting worse

You can call 111 or get help from 111 online .

What we mean by severe pain
Severe pain:
  • always there and so bad it's hard to think or talk
  • you cannot sleep
  • it's very hard to move, get out of bed, go to the bathroom, wash or dress
Moderate pain:
  • always there
  • makes it hard to concentrate or sleep
  • you can manage to get up, wash or dress
Mild pain:
  • comes and goes
  • is annoying but does not stop you doing daily activities

Treatments for pressure ulcers

How a pressure ulcer is treated depends on how severe it is.

Changing position and moving regularly is important to help relieve pressure on the ulcers and help stop new ones forming.

Other treatments include:

  • specially designed mattresses and cushions
  • dressings to protect the ulcer and help it heal
  • creams and ointments
  • antibiotics if the ulcer is infected
  • cleaning the ulcer

If the pressure ulcer is severe or other treatments have not worked, you may need to have surgery to clean and close the ulcer.

Causes of pressure ulcers

Pressure ulcers are caused by something putting pressure on or rubbing your skin.

It can happen to anyone, but it's usually if you have problems moving, as this can mean the weight of your body is always putting pressure on the same areas of skin, which can damage it.

You have a higher chance of getting a pressure ulcer if you:

  • have problems moving
  • have had a pressure ulcer before
  • have been seriously ill in intensive care or have recently had surgery
  • are underweight
  • have swollen, sweaty or broken skin
  • have poor circulation or fragile skin
  • have problems feeling sensation or pain

Things you can do to prevent pressure ulcers

If you're being cared for at home, there are things you and your care team can do to lower your chances of getting a pressure ulcer.

Do

  • change position regularly

  • use specially designed mattresses and cushions

  • check your skin every day for symptoms of a pressure ulcer

  • try to stay active, if possible

  • eat a healthy, balanced diet

Don't

  • do not smoke

Prevention

Symptoms of a pressure ulcer are discoloured patches on the skin, which can feel painful, warm, spongy or hard.

Treatments for pressure ulcers include protective dressings, creams and antibiotics if the ulcer is infected. Surgery is sometimes also needed.

Pressure ulcers are caused by pressure on your skin. If you have difficulty moving, the pressure of your body weight on your skin can cause ulcers.

Changing position regularly and using special mattresses and cushions can help prevent pressure ulcers.
