Cellulitis is a common bacterial skin infection. Cellulitis may first appear as a red, swollen area that feels hot and tender to the touch. The redness and swelling often spread rapidly. Cellulitis is usually painful.
In most cases, the skin on the lower legs is affected, although the infection can occur anywhere on your body or face. Cellulitis usually affects the surface of your skin, but it may also affect the underlying tissues of your skin. Cellulitis can also spread to your lymph nodes and bloodstream.
If cellulitis isn’t treated, the infection might spread and become life-threatening. You should get medical help right away if you experience the symptoms of cellulitis.
The symptoms of cellulitis may include:
Some common symptoms of a more serious cellulitis infection are:
Symptoms such as the following could signal that cellulitis is spreading:

Cellulitis occurs when certain types of bacteria enter through a cut or crack in the skin. Cellulitis is commonly caused by Staphylococcus and Streptococcus bacteria.

Your doctor will usually prescribe a 10- to 21-day regimen of oral antibiotics to treat your cellulitis. The length of your treatment with oral antibiotics will depend on the severity of your condition. Even if symptoms improve within a few days, it’s important to take all of the medication prescribed to ensure proper treatment. While you’re taking antibiotics, monitor your condition to see if symptoms improve. In most cases, symptoms will improve or disappear within a few days.
In some cases, pain relievers are prescribed. You should rest until your symptoms improve. While you rest, you should raise the affected limb higher than your heart to reduce any swelling.
Contact your doctor immediately if you don’t respond to treatment within three days after beginning a round of antibiotics, if your symptoms get worse, or if you develop a fever.
Cellulitis should go away within seven to 10 days of starting antibiotics. Longer treatment could be necessary if your infection is severe. This can occur if you suffer from a chronic disease or if your immune system isn’t working properly.
People with certain pre-existing medical conditions and risk factors may need to stay in the hospital for observation during treatment. Your doctor may advise hospitalization if you:

If you have a break in your skin, clean it immediately and apply antibiotic ointment regularly. Cover your wound with a bandage and change it daily, until a scab forms. Watch your wounds for redness, drainage, or pain. These symptoms could indicate an infection.
