– About Normal and Varicose Veins –
Normally circulating blood flows back from your feet, and lower legs, through deep veins that eventually reach the heart. As this blood must flow against the effects of gravity, these veins contain structures called valves which help prevent blood flowing backwards toward the feet. Sometimes these valves become damaged, or the walls of the deep veins become thin. The valves then become leaky, and back pressure of blood occurs. Veins in the legs, ankles and feet can swell, becoming what we call varicose veins. These can be painful, and look unattractive. Complications such as venous ulcers can occur, so it is wise to have this problem treated. Nowadays this is straightforward and virtually painless.

We all have a circulatory system which gets blood from the heart to our organs and tissues, along thick-walled arteries. Blood reaches our feet relatively easily, if our arteries are healthy.
Varicose veins are enlarged or swollen veins on the legs or feet, which are caused by damage to the valves in the deep veins of the leg.
Why Treat Varicose Veins?
The pain, aching and swelling experienced by many people because of varicose veins may not unfortunately now qualify them for NHS treatment.
