Swollen legs due to primary lymphoedema. This is an abnormal accumulation of lymph in the tissue, and is caused by a blockage or damage to the lymphatic vessels. Although some cases have a known trigger (such as cancer, damage or removal by radiotherapy or surgery, etc.), many cases are of unknown cause. There is no specified treatment for lymphoedema. Management is by diuretic drugs, or massage and exercise of the affected limbs. In very severe cases, where the swelling causes disability, tissue may be removed surgically.
