** Thanks for contacting with your health concern 1. since you are a diagnosed case and under the vascular surgeon opinion, thus probably he has to exclude that whether it is a blood clot [DVT- deep vein thrombosis, since the clot could break free and travel up to the lungs to cause fatal embolism] or something else like: - arterial: due to poor circulation in the arteries. - diabetic: due to high blood sugar. - vasculitic: due to any inflammatory disorder OR - traumatic: due to injury to the leg. PS. one has to also exclude venous insufficiency [incompetence of the valves] as the cause of the same, so management will depend on the cause, until then - keep your legs elevated [whenever possible] - limit salt intake. - maintain proper hydration.
