What is cellulitis?

Cellulitis is a bacterial infection of the skin which can occur in any location but usually is seen on the feet or legs.  Red, swollen, tender skin is always present.  It begins as a small area but rapidly spreads out from the initial site.

Cellulitis begins when bacteria enter a break or crack in your skin, such as where you've had recent surgery, cuts, puncture wounds, an ulcer, athlete's foot or dermatitis.  Other causes of broken skin are insect and spider bites and severely dry, cracked skin .

Who is at risk of developing cellulitis?

Older people with circulatory problems, those with a weakened immune system (HIV, cancer), people with diabetes or diabetic foot ulcers, or IV drug abusers are all at higher risk.

What if I think I have cellulitis?

Try to see your physician the same day.  If this is impossible, seek care at an Urgent Care or Emergency Room because cellulitis can rapidly develop into a bloodstream infection and spread throughout your body. Your doctor may have to make sure you do not have a blood clot in the leg since the symptoms of swelling and pain can be similar.  Cellulitis is caused by the same organism that produces the "flesh-eating disease" so your doctor will take cultures and evaluate you for this condition also.

What is the treatment for cellulitis? 

Treatment of cellulitis always requires antibiotics.  If the physician feels it's more urgent, intravenous antibiotics may be ordered or the patient may be hospitalized.  It is important to finish the entire course of antibiotic even though the symptoms look better after a few days.
