Cellulitis
A spreading area of red, warm, tender skin. A bacterial infection that needs prompt care.
In short
Cellulitis is a bacterial skin infection that needs prompt antibiotics and monitoring. Caught early, most cases do well, but spreading or severe infection is a medical emergency, so safety-netting matters.
Overview
What is cellulitis?
Cellulitis is a bacterial infection of the deeper layers of the skin and the tissue beneath it, usually caused by bacteria entering through a break in the skin. It causes a spreading area of red, warm, swollen, tender skin, most often on the lower leg. It needs antibiotics, and because it can become serious, it should be assessed promptly.
Symptoms
Common symptoms
- An area of skin that is red, warm, swollen, and tender
- Redness that spreads over hours
- Pain in the affected area
- Sometimes a fever or feeling unwell
- Often on the lower leg, but can be anywhere
When to act
When to see a doctor
Book promptly if you have a spreading area of red, warm, tender skin. Go to A&E or call 999 for rapidly spreading redness, severe pain, blistering or dusky skin, a high fever, confusion, or facial/eye involvement.
When to seek urgent help
Seek urgent help if
- Rapidly spreading redness, severe pain out of proportion, or the skin turning dusky or blistered (possible serious infection, go to A&E)
- A high fever, shivering, confusion, or feeling very unwell (call 111 or 999)
- Cellulitis around the eye or on the face (needs urgent assessment)
- Redness that keeps spreading despite antibiotics
Call 999 for life-threatening emergencies or NHS 111 for urgent non-emergency advice.
