Normally, veins are elastic, meaning that they stretch and snap back to their normal size. When they lose the ability to snap back to their normal size, they become dilated permanently. Most varices occur in the legs, although they can be present at other sites. Compression hose acts as an external skeleton, compressing the leg and providing support for the weakened veins. By providing external support, the tissues tend not to swell as much, and the discomfort is better controlled.
