Cellulitis
Cellulitis is an infection of the deep layers of skin. A break in the skin, such as a cut or scratch, can let bacteria under the skin.
Cellulitis causes the affected skin to become red, swollen, warm, and sore. The reddened areas have a border you can see. An open sore may leak fluid (pus). You may have a fever, chills, and pain.
Cellulitis is treated with antibiotics taken for 7 to 10 days. An open sore may be cleaned and covered with cool wet gauze. Symptoms should get better 1 to 2 days after treatment is started. Make sure to take all the antibiotics for the full number of days until they are gone. Keep taking the medicine even if your symptoms go away.
If not treated, cellulitis can get into the bloodstream and lymph nodes. The infection can then spread throughout the body. This causes serious illness.
Home care
Follow these tips:
-
Limit the use of the part of your body with cellulitis.
-
If the infection is on your leg, keep your leg raised while sitting. This helps reduce swelling.
-
Take all of the antibiotic medicine exactly as directed until it is gone. Don't miss any doses, especially during the first 7 days. Finish taking all of the medicine even when your symptoms get better.
-
Keep the affected area clean and dry.
-
Wash your hands with soap and clean, running water before and after touching your skin. Anyone else who touches your skin should also wash his or her hands. Don't share towels.
Follow-up care
Follow up with your healthcare provider, or as advised. If your infection doesn't go away after finishing the first antibiotic, your healthcare provider will prescribe a different one.
