Hello, Thanks for writing to us. This is because standing and walking puts extra pressure on the veins in the lower body.If your varicose veins are causing you pain or discomfort or they cause complications, they can be treated in several ways, the most common being: endothermal ablation - treatment where heat is used to seal affected veins sclerotherapy, which uses special foam to close the veins a phlebectomy, involving surgery to remove the affected veins compression stockings - specially designed to improve circulation in the legs I do hope that you have found something helpful and I will be glad to answer any further query.
