The raised veins on both sides of the forehead, which are called veins in medicine, are mainly due to anatomical characteristics. Since the subcutaneous blood vessels in the forehead are superficially located and there is relatively little subcutaneous tissue, they appear to be raised, especially when drinking alcohol, exercising, taking a sauna, and being emotionally irritable. Most commonly, in infants and young children, the veins next to the forehead are often punctured during venous blood collection or intravenous infusions because the veins are not easy to find. There is also a similar bruising of the dorsum of the foot and foot, which is similar in principle, but is fundamentally different from varicose veins of the lower extremities. Varicose veins in the lower extremities are mainly due to the dilatation of blood vessels caused by valve insufficiency, which is a pathological change, but the bruised veins on both sides of the forehead are a normal physiological reaction and do not require special treatment.
