Varicose veins are treated by bloodletting, which is not a formal treatment and lacks evidence-based medical evidence, so it is not generally used in clinical practice. For patients with varicose veins, because of the lack of evidence-based medicine, and the lack of corresponding case reports, if not handled properly, there is a risk of venous inflammation, and even venous thrombosis, so varicose veins still need to go to the regular hospital for diagnosis and treatment. Clinically, when varicose veins are more serious, surgery is usually chosen; when they are mild, they can be treated by wearing venous stockings or injecting foam sclerotherapy, etc. The medication should be administered under the guidance of a professional doctor and should not be used without authorization. Varicose veins in all parts of the body should be treated in regular hospitals under the guidance of specialized doctors.
