Varicose veins are common and usually nothing to worry about. For many people, the twisted and enlarged bluish or purplish veins visible near the surface of the skin are simply a cosmetic concern.
But if you are experiencing pain or discomfort, this could be a sign of a more serious problem.
Varicose veins usually occur in the legs, specifically on the inner thighs or the bottom of your calves. They are caused by increased blood pressure in the veins for a prolonged period.
Arteries carry blood away from your heart to the rest of your body, and veins bring blood back to the heart. Your veins contain valves that help to regulate the blood flow back to the heart.
If your veins or valves are weak or damaged, blood doesn’t flow properly. Pressure can build up, resulting in dilation of the veins and swelling in the legs and feet. Over time, there is a risk of developing ulcers or even blood clots.
In their milder form, varicose veins are commonly known as spider veins.
