Earthworm legs are called varicose veins of the lower limbs. Varicose veins with mild clinical symptoms can be treated with injections, while serious varicose veins need surgical treatment. 1. Varicose veins of the lower limbs can be improved by taking oral medication to improve the veins of the lower limbs such as Mazolin when the clinical symptoms are mild in the early stage and wearing compression stockings to avoid further aggravation of the varicose veins. In addition, sclerosing agent can be injected to embolize the branches of veins in the area of varicose veins, but since it is not possible to treat severe varicose veins, injections are not effective for all varicose veins. 2. Severe varicose veins not only cause discomfort such as swelling and pain in the lower limbs, but also cause hyperpigmentation and skin ulcers in the foot and ankle area, etc. Therefore, most of the severe varicose veins need surgical treatment, such as Varicose Vein High Ligation + Endothelial Stripping, which can completely dislodge the diseased veins. Therefore, varicose veins of the lower limbs need to be treated at the earliest possible time in the hospital and according to the degree of varicose accordingly.
