But if bulging varicose veins are causing you pain, look into a simple procedure called sclerotherapy, which is covered by many health-insurance plans. (I know, because I just had it done!)

He or she can refer you to a specialist. More from Prevention: An Olympian Opens Up About Her Varicose Veins
