Weeping of the lower legs, what causes it and what home remedy is good for it?

Very advanced edema: The causes of this are fairly serious problems in the vascular system. Sufficient blockage creates so much lymphatic back-pressure that vessels rupture and fluid seeps out finally through the skin. The internal damage is fairly advanced by this time so other than actions/positions that might feel a bit less painful. Raised leg positions & compression socks might still help some. See a dr for help.
