A lot of red blood on the legs is actually a mild manifestation of varicose veins. Varicose veins are mainly due to congenital weakness of the vein walls, intravenous hypertension, and venous valve insufficiency, resulting in tortuous and dilated superficial veins in the lower extremities. In its early stages, there may be some reticular vessels, or capillary dilation, forming the manifestation of a lot of red blood on the legs. This condition usually has no serious consequences and is mainly treated conservatively. However, for young women, it can affect the aesthetics and can be a headache. The main treatment is to delay its further development and avoid causing severe varicose veins. Patients are clinically advised to elevate the affected limb, avoid prolonged sitting and standing, and can wear medical compression stockings to prevent its further progression. If the condition is of great concern to some young women, they can also try to apply treatments such as sclerotherapy to lift and subside the redness. However, sclerotherapy will inevitably also leave traces of hyperpigmentation or scarring, so care needs to be taken when choosing.
