In varicose veins, the darkening of the feet is due to the dysfunction of the skin caused by the varicose veins and the leakage of blood from the veins to the subcutaneous level, which can cause damage to the skin, eczema, itching and skin pigmentation. If these conditions occur, they can be treated conservatively, mainly by wearing varicose veins elastic stockings and medication, mainly oral Veritin and Diosmin and topical Xanax, which can effectively alleviate the further development of the disease. For complete cure, surgical treatment is required. There are various surgical methods, including the traditional saphenous vein ligation with segmental stripping, laser radiofrequency treatment of the main saphenous vein, and injection of sclerosing agents into the branch veins to treat the varicose veins, which can effectively slow down the progression of the disease and improve the darkened areas of the skin.
