The answer to your question is yes. I tell my patients that arteries carry blood away from the heart to the body. Arteries Supply oxygen and nutrients to the body's organs and tissue. The body needs nutrients and oxygen therefore the arterial blood is pumped to the body. Once oxygen and nutrients have been extracted from the arterial blood it enters the venous system starting at the skin level. The sole purpose of veins is to bring the blood back to the heart. This is done through one-way valves in the venous system. Only 10% of your venous blood should be in your superficial system. This is the skin and fatty tissue. 90% of your venous blood should be in the Deep system. Deep system veins run between your muscles. Every time your muscles contract it pushes blood back to the heart where it can receive more oxygen to be pumped to the body. When the valves in your superficial system fail to close and hold the blood in the Deep system, deep system blood backs up into the superficial system which is your fatty tissue and skin. When this happens the Superficial veins will become large and overtime they will become diseased and leak out protein which draws water into the fatty tissue and hemosiderin which begins to tattoo the skin. These are the skin changes that many people will see along with varicose veins and large spider veins. So in the morning after you have been lying down all night your legs will look the best. Because the blood has been able to flow back to the heart. In the upright position your valves are required to hold the blood in the deep system. When you go to work and sit all day or stand all day, blood will pool in your legs because the valves are not holding that blood in the Deep system where it can be pumped back to your heart. This leads to swelling in the legs. Depending on how many valves are not working will determine how quickly you develop swelling. Some people will develop it immediately after getting out of bed, some will develop it in the early afternoon and some will develop it at night. Additionally people will complain of dull aching pain at night time, restless leg syndrome, itching, burning, numbness, heaviness in the legs and fatigue as the day goes on. When you complain of swelling to your primary care doctor most of the time you will be evaluated for heart disease, lung disease ,liver disease and kidney failure. These are other causes of swelling in the legs and are more detrimental to your health. Venous disease often does not kill you it is just debilitating. Venous disease has a slightly higher increase risk for deep Venous Thrombosis. Most patients if they present with swelling will often be sent for venous duplex to rule this out. This is because a deep Venous Thrombosis has the potential to move up the venous system into the lungs and cause a pulmonary embolus which can be lethal. If you have swelling regardless of external findings the easiest thing to do is wear graded compression stocking (20-30 mmhg) when you are working, sitting, standing for long periods of time, long car rides or plane ride. Finally get a vein mapping of your legs which will diagnose the problem and allow it to be treated. When you have symptoms it is not considered cosmetic. When it is worked up properly treatment is covered by most insurances including medicare.
