Cellulitis is a sudden, non-contagious, bacterial infection of the tissues under the skin. Infection can enter the body through a break in the skin, fungal infections (under nails), or an existing wound or skin inflammation.
Keeping the skin clean, well-moisturized, and intact reduces the risk of these entry points forming. Good skin care practices—like gentle cleansing, daily moisturizing, prompt treatment of cuts or fungal infections, and protecting the skin from injury—help maintain the skin’s barrier function. This is especially important because recurrent cellulitis can worsen lymphedema over time, creating a cycle of swelling and infection.
Signs and symptoms of cellulitis include:
- Rapid onset of skin redness, swelling or pain
- Skin that feels hot or painful to the touch or tingling
- Skin that is red or with a reddish rash or red streaks or swollen
- A feeling of tiredness or heaviness
- If cellulitis worsens, you may feel flu-like symptoms, feelings of nausea, fever or chills
IMPORTANT: If you notice any of these symptoms, seek medical help without delay. Cellulitis can spread quickly and requires antibiotic treatment.
People with lymphedema are at risk for cellulitis because their lymphatic system is less able to fight infection. By prioritizing skin care, individuals with lymphedema can significantly lower their risk of cellulitis and support more stable, long-term management of their condition.
