Are Itchy Varicose Veins Dangerous?

No. One of the most common symptoms of varicose veins is itching, and the symptoms are caused by the pooling of the blood where the faulty valves allow the blood to flow back down the vein towards the feet. The pooling of blood causes an increase in pressure inside the vein, which leads to these symptoms. The symptoms are not dangerous, however they can be very uncomfortable.
