If you're not sure it's cellulitis

Other conditions can make your skin red, flaky and blistered.

It's unlikely to be cellulitis unless part of your skin is hot, red and swollen.

Treatment from a GP

For mild cellulitis affecting a small area of skin, your GP will prescribe antibiotic tablets – usually for a week.

Your symptoms might get worse in the first 48 hours of treatment, but should then start to improve.

It's important to keep taking antibiotics until they're finished, even when you feel better.

Most people make a full recovery after 7 to 10 days.

If your cellulitis is severe, your GP might refer you to hospital for treatment.

Things you can try

As well as taking antibiotics for cellulitis, you can help speed up your recovery by:

  • taking paracetamol or ibuprofen for the pain
  • raising the affected body part on a pillow or chair when you're sitting or lying down to reduce swelling
  • regularly moving the joint near the affected body part, such as your wrist or ankle, to stop it getting stiff
  • drinking plenty of fluids to avoid dehydration
  • not wearing compression stockings until you're better

You can reduce the chances of getting cellulitis again by:

  • keeping skin clean and well moisturised
  • cleaning any cuts or wounds, or using antiseptic cream
  • preventing cuts and scrapes by wearing appropriate clothing and footwear
  • wearing gloves if working outside

Cellulitis complications

If not treated quickly, the infection can spread to other parts of the body, such as the blood, muscles and bones.

Call 999 or go to A&E now if you have cellulitis with:

  • a very high temperature, or you feel hot and shivery
  • a fast heartbeat or fast breathing
  • purple patches on the skin
  • feeling dizzy or faint
  • confusion or disorientation
  • cold, clammy, pale skin
  • unresponsiveness or loss of consciousness

These are symptoms of sepsis, which can be very serious and potentially life threatening.

Causes

Cellulitis is usually caused by a bacterial infection.

The bacteria can infect the deeper layers of your skin if it's broken – for example, because of an insect bite or cut, or if it's cracked and dry.

Sometimes the break in the skin is too small to notice.

You cannot catch cellulitis from another person as it affects the deeper layers of the skin.

You're more at risk of cellulitis if you:

  • have poor circulation in your arms, legs, hands or feet – for example, because you're overweight
  • find it difficult to move around
  • have a weakened immune system because of chemotherapy treatment or diabetes
  • have bedsores (pressure ulcers)
  • have lymphoedema, which causes fluid build-up under the skin
  • inject drugs
  • have a wound from surgery
  • have had cellulitis before

People who are more at risk of cellulitis should treat any athlete's foot promptly.
