Cellulitus

Cellulitis is a common and sometimes painful bacterial skin infection. It may first appear as a red, swollen area that feels hot and tender to the touch. The redness and swelling can spread quickly. It most often affects the skin of the lower legs, although the infection can occur anywhere on your body or face.

Causes

Cellulitis is usually caused by a bacterial infection. The bacteria can infect the deeper layers of your skin if it's broken, for example, because of an insect bite or cut, or if it's cracked and dry. The most common bacteria that cause cellulitis are Streptococcus and Staphylococcus ("staph"), the same bacteria that can cause impetigo and other diseases.

Symptoms

Symptoms of cellulitis include redness, swelling, warmth, and pain in the affected area. You might also have a fever and feel generally unwell. If the infection isn't treated, it can spread to your lymph nodes and bloodstream and rapidly become life-threatening. It can also spread to other parts of your body.

Treatment

Treatment for cellulitis usually involves taking antibiotic medication. Most people who are treated in the early stages of the infection usually recover fully without any long-term problems. However, if left untreated, cellulitis can be severe and potentially life-threatening.

Prevention

Preventing cellulitis involves taking care of your skin and keeping it clean and moisturized. Avoid scratching or picking at your skin, and keep any cuts or wounds clean and covered until they heal. If you have a skin condition like eczema or athlete's foot, treating it can help prevent cellulitis.
