Varicose veins cold gel is not useful for the treatment of varicose veins, but can be used mainly to relieve some of the discomfort, such as local skin swelling and fever caused by varicose veins. Varicose veins are caused by blood stagnation in the venous cavity and weakness of the venous walls resulting in dilated and tortuous blood vessels. As a result, the blood vessels protrude from the skin, the lower limbs may feel sore and swollen, and there may even be symptoms such as hyperpigmentation, rash, desquamation, and ankle edema. Mild varicose veins are usually asymptomatic and do not require special treatment, and the discomfort can be relieved by wearing compression stockings on the advice of a doctor. They can also be treated with laser or sclerotherapy if necessary. If you notice significant symptoms in the skin around varicose veins, such as significant soreness, swelling, hyperpigmentation, and edema in the lower extremities, you should consider the possibility of deep vein thrombosis and seek immediate treatment. For severe varicose veins, treatment options usually available include high saphenous vein ligation and stripping surgery, minimally invasive endovenous laser ablation or radiofrequency ablation, and minimally invasive mechanical chemical ablation. Patients with varicose veins should pay attention to weight control and eat more high fiber foods to prevent constipation in their daily life. If you need to stand for a long time, you should move your legs occasionally to promote blood circulation or wear elastic stockings prophylactically.
