The most common problems with varicose veins are:
The condition is most commonly a result of a varicose vein. A varicose vein is a blood vessel that does not have a healthy blood supply. When blood supply to a vein does not support blood flow into the body, the blood can pool in the vein and not be absorbed or used by the body. When veins become varicose, they become narrow and may be filled with a clear liquid (such as a milky-white substance called a varicose flow). The liquid is not a fluid at all, it is a solution of minerals such as calcium and sodium. Some patients may have blood clots, but these clots may also block the flow of the blood to the vein. The problem is that many people don't know what a varicose flow is, so they don't see any symptoms from the condition. They don't know that the veins become narrowed and then filled with clear fluid when the blood flow is blocked by blood clots. When a varicose vein becomes narrow and filled with a liquid, it is very important to see a doctor and have it checked out. If this condition is suspected, a doctor may perform a blood test to look for problems with the veins.
