Cellulitis is a common skin infection that happens when bacteria spread through the skin to deeper tissues. Most cases are mild and last several days to a couple of weeks. But cellulitis can sometimes progress to a more serious infection, causing severe illness that affects the whole body (sepsis) or other dangerous problems.
Treatment is needed to help control the infection and reduce symptoms.
Some people are at higher risk for cellulitis, such as those who have diabetes, a weakened immune system, or edema. They also tend to get sicker from cellulitis. And they are more likely to get cellulitis again.
Cellulitis may be treated without doing tests to find out what caused it. But your doctor may do tests, if needed, to look for a specific bacteria, like methicillin-resistant Staphylococcus aureus (MRSA).
The doctor has checked you carefully, but problems can develop later. If you notice any problems or new symptoms, get medical treatment right away.
