About Varicose Veins 

​Veins are blood vessels that return blood from the rest of the body to the heart. They are a network throughout the tissues of the body. Just like any other part of the human body things can go wrong and the veins don't function the way they should.
​Varicose veins are the most common problem that arise and are a very common vascular condition. Everyone will know or remember a friend or family member with bulging veins down their leg. The bulging and twisting of these large veins is caused by failure of one-way valves in the vein system and an increase in pressure in the vein. (see figure right)
​Apart form their physical appearance, they often cause symptoms and can, in some people, cause significant skin changes around the calf and ankle; even ulceration. Mostly though the symptoms are more subtle; it is often only after they've been treated, and the symptoms have gone, that the severity of the symptoms become apparent.
