Swelling in the legs can be caused by bad veins with valves that no longer work, injury from prior blood clot or phlebitis, weak muscles that pump the blood up the leg, or increased pressure in other organs such as your heart.
In order to heal your wound you were placed in some form of compression wrap. Once your scar was mature enough to handle pressure from socks you were prescribed support hose. Even though we live in Phoenix where temperatures often exceed 100ºF the compression is needed to fight the swelling. Surgery is often used for bad veins, but even so support hose are a required part of this treatment. There is no way around it, you will have to wear some form of compression garment.
