Symptoms

Possible signs and symptoms of cellulitis, which usually occur on one side of the body, include:

• Red area of skin that tends to expand
• Swelling
• Tenderness
• Pain
• Warmth
• Fever
• Red spots
• Blisters
• Skin dimpling

When to see a doctor

It's important to identify and treat cellulitis early because the condition can spread rapidly throughout your body.

Seek emergency care if:

• You have a red, swollen, tender rash or a rash that's changing rapidly
• You have a fever

See your doctor, preferably that day, if:

• You have a rash that's red, swollen, tender and warm — and it's expanding — but without fever
