Cellulitis may develop and spread for a period of 2 to 4 days. If treated promptly with antibiotics, the infection usually clears up within 1 or 2 weeks.

Cellulitis that is not properly treated may lead to bacteria getting into your blood stream, blood poisoning, areas of destroyed body tissue, amputation of the affected body part, and death.

If you were prescribed an antibiotic, take all of it as prescribed.  Ask your doctor how to care for the infected area. For example, ask if you should put hot packs or dressings on the area.  Sometimes the infection may get worse even though you are taking an antibiotic. Ask your doctor what symptoms you should watch for and when you should check back with your doctor.  If your infection does not clear up or if new symptoms develop, contact your doctor.

Clean cuts, abrasions, and other skin injuries thoroughly with antiseptic soap.  Keep wounds and sores clean and protected with a bandage. Remember to change the bandage daily or sooner if it becomes dirty or wet.  See your doctor for treatment as soon as possible if a wound or sore shows signs of infection. If you have diabetes, follow your instructions for good skin care and keep your blood sugar under good control (within the recommended range).
