Yes, absolutely! While varicose veins can go untreated for a while, they are a ticking time bomb and should be evaluated by a vein doctor immediately. In the early stages, varicose veins are a sign of poor circulation and can lead to chronic venous insufficiency, skin ulcers, bleeding, or blood clots. During the final or severe stages of varicose veins, the pooling of blood and increased pressure causes severe complications namely : Deep Vein Thrombosis (DVT). DVTs are a serious medical condition – they are a blood clot deep in the veins. These blood clots can break loose and travel to your lungs, causing a life life-threatening pulmonary embolism, and even become fatal.
