With antibiotic treatment, cellulitis heals within seven to 10 days, according to Healthline. Symptoms, such as warmth, redness and swelling may be alleviated within three days of treatment, notes to UpToDate. Cellulitis is a bacterial skin infection.

Physicians may prescribe a one- to two-week course of antibiotics for cellulitis, according to UpToDate. Individuals with cellulitis can hasten healing and reduce swelling by keeping the infected area elevated above heart level. The infected area also should be kept clean and dry.

If symptoms worsen or persist longer than three days, the patient should contact a physician immediately, states Healthline. Cellulitis can spread to other areas of the body and cause complications such as blood infection and tissue death.
