Is an ice pack or heat pack better to relief varicose vein leg pain?

Heat but it depends: Before advising either you need a specific diagnosis. Why is it vein pain? Could be some other reason pain is the vein swollen red and hot? Other important things can cause pain in the leg like blood clots, muscle inflammation, and other and you need to have your physician check it

Which ever gives you: relief. Neither is a treatment for varicose veins, but to help relieve symptoms. Be careful not to burn yourself, low heat & ice with a towel between ice & skin.

Heat and VV: For discomfort associated with varicose veins heat is better than cold. If you are having pain from your varicose veins then you should see a vein specialist for a venous evaluation including a venous ultrasound to make sure that you do not have thrombophlebitis.
