Fluid retention, typically in the arms or legs, due to blockage of the lymphatic system; symptoms include swelling, feeling of heaviness or tightness, aching or discomfort, and hardening of the skin
Swelling, typically in one arm or leg, due to blockage of the lymphatic system (a drainage network that helps with the immune system), leading to backed up lymphatic fluid in the tissues. Some types of lymphedema are inherited, while others are caused by surgery, radiation therapy, or swelling of the lymph nodes due to infection or cancer.
