Why would varicose veins change size?

I have a few varicose veins on both of my legs. Sometimes I can barely see them, and then at other times, they stick out a ton and look ugly. Why would the veins change size?

Varicose veins can easily fill and will hold blood, but are no longer effective in the vein's primary role of effective venous blood flow back towards the heart. In the morning, since you have been laying down, the varicose veins will be drained and at a minimal volume. As you are standing during the day the blood accumulates in the varicose veins, making them more visible and often tender or aching. Walking and movement will help to lift blood out of the legs and back to the heart. Compression hose can also help by limiting the varicose veins ability to expand, fill and hold blood.

Veins help dissipate heat! This means that the hotter you are, the more superficial they appear to help you cool off more. Veins are also capacitance vessels like a water tower. The more hydrated you are, the larger they appear. The more dehydrated you are, the more they disappear.
