Symptoms of cellulitis

Cellulitis makes your skin painful, hot and swollen. The area usually looks red, but this may be less obvious on brown or black skin.

Your skin may also be blistered, and you can also have swollen, painful glands.

You can get cellulitis on any part of your body, such as:

Swollen, tight, red skin on the fingers and back of 1 hand caused by cellulitis. Shown on white skin.

Eye – which is very serious. The white part of your eye may become red, but this does not always happen.

Treatment for cellulitis

For mild cellulitis affecting a small area of skin, a doctor 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.

Contact a GP if you do not start to feel better 2 to 3 days after starting antibiotics.

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 cellulitis is severe, you might be referred to hospital for treatment.

To stop cellulitis recurring

Some people with recurring cellulitis might be prescribed low-dose long-term antibiotics to stop infections coming back.

What causes cellulitis

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.
