Cellulitis is a common skin infection that happens when bacteria spread through the skin to deeper tissues. Most cases are mild and last several days to a couple of weeks. But cellulitis can sometimes progress to a more serious infection, causing severe illness that affects the whole body (sepsis) or other dangerous problems.

Treatment is needed to help control the infection and reduce symptoms.

Some people are at higher risk for cellulitis, such as those who have diabetes, a weakened immune system, or edema. They also tend to get sicker from cellulitis. And they are more likely to get cellulitis again.

At first, the infected area will be warm, red, swollen, and tender. If the infection spreads, you may have a fever, chills, and swollen lymph nodes.

Cellulitis can occur anywhere on the body. In adults, it often occurs on the legs, face, or arms. In children, it is most common on the face or around the anus.

Cellulitis is treated with antibiotics. If the infection is mild, you may be able to take antibiotic pills at home.

If the infection is severe, you may need to be treated in a hospital so that you can get I.V. antibiotics directly into your bloodstream, along with any other care you may need.

Be sure to follow your doctor's instructions about medicine and skin care. To help with your recovery and to feel better:

• Take all of your medicine as prescribed. Don't stop taking it just because you feel better. You need to take the full course of antibiotics.
• Elevate the affected area to reduce swelling. Warm compresses may also help.
• Use pain relievers as needed.
