Cellulitis is an infection of the skin and deep underlying tissues. Group A strep (streptococcal) bacteria are the most common cause. The bacteria enter your body when you get an injury such as a bruise, burn, surgical cut, or wound. Several factors can place you at greater risk of developing cellulitis, including:
- Injuries, including cuts, fractures, or burns
- Skin disorders, such as eczema, athlete’s foot, chicken pox, and shingles
- Chronic swelling of your arms or legs
- Intravenous drug use
Symptoms of cellulitis can include:
- Fever and chills
- Skin dimpling
- Swollen glands or lymph nodes
- A rash with painful, red, tender skin. The skin may blister and scab over.
Cellulitis is usually treated with antibiotics. They may be oral in mild cases, or intravenous (through the vein) for more severe cases. Other treatments include cleaning the affected area, elevation, and ointments.
