What are varicose vains?
Varicose veins are caused by a protein that forms when blood gets sucked up by the veins and then returns to the heart. This can cause a blockage in the blood vessel. The blocked blood vessel can then cause a sudden heart attack.
The most common symptoms are redness and swelling of the veins, which can be deep or superficial, or they may feel like small clots, but they don't usually have any blood clots. The problem is most often caused by a blood clot that forms near a large vein or artery (valvular blockage). If the clot blocks the blood vessel, the blockage is sometimes called aneurysm. Varicose vains can be caused by heart disease, diabetes, a blood clotting disorder, or a medical procedure. In the United States, varicose vains are most often caused by varicose veins, which are located in the legs. If you have varicose veins, you can develop varicose vains from other serious medical problems, such as aneurysm or a heart attack. In addition, varicose vains are usually diagnosed when a doctor thinks they're caused by a medical condition. Your doctor may use a blood test to find out if the varicose vein is causing the varicose vains.
