They are called varicose veins and they are a result of faulty valves in the veins that allow blood to pool or flow back instead of going forward and the vein then bulges.

Any cure for swollen legs due to water retention?

Swollen legs are often due to weakness of the leg veins which have to circulate the blood against gravity. When they are weak, blood pools in the veins so that fluid leaks into the tissues. This causes swollen legs. Pregnancy causes swollen legs due to the weight of the baby on the pelvic veins. Kidney problems and heart problems can also cause swollen legs and ankles. If the problem is not due to pregnancy, and if your doctor confirms that your heart and kidneys are ok, then don't take diuretics as they can make the problem worse.
