Cellulitis is a deep bacterial infection of the skin. The infection usually involves the face, or the arms and legs. It may happen in normal skin, but it usually occurs after some type of trauma causes an opening in your skin. This opening can lead to an infection.

Treatment for cellulitis
Specific treatment for cellulitis will be determined by your doctor based on:

Your age, overall health, and medical history
Extent of the disease
Your tolerance for specific medications, procedures, or therapies
Expectations for the course of the disease
Your opinion or preference
Immediate treatment can help prevent the spread of cellulitis. Treatment may include:

Antibiotics
Cool, wet dressings on the infection site
Surgical intervention
If there is an extremity (arm or leg) that is affected, your doctor may have you elevate the extremity and decrease the amount of activity
Rest
Based on the physical examination, your doctor may treat in the hospital depending on the severity of the cellulitis.
