This type of swelling occurs when lymph, a fluid that contains white blood cells and defends against germs, builds up in your body’s soft tissues. It can build up when the lymph system is damaged or blocked and usually happens in the arms or legs. Causes of lymphedema include:
- Infection
- Cancer
- Scar tissue from radiation therapy or surgical removal of lymph nodes
- Inherited conditions in which lymph nodes or vessels are absent or abnormal
Lymphedema signs and symptoms, which occur in your affected arm or leg, include:
- Swelling of part or all of your arm or leg, including fingers or toes
- A feeling of heaviness or tightness
- Restricted range of motion
- Aching or discomfort
- Recurring infections
- Hardening and thickening of the skin (fibrosis)
Treatment can help control symptoms and includes exercise, compression devices, skin care, and massage.
