Hello Interloper!

The cause of varicose veins lies in a fault with the valves present in the veins of the leg.
If these valves malfunction, the blood flowing through the leg flows down rather than up.
In the past, the treatment offered has consisted of surgical intervention, with the vein in question actually being stripped out of the leg - an unpleasant operation that took a long time to recover from and had a high rate of recurrence of the veins.
