Question: What is the difference between spider veins, reticular veins and varicose veins? Answered by vascular surgeon Jonathan Thompson, MD.

If your legs ache and swell by the end of the day, you might have chronic venous insufficiency (CVI). Understanding this common condition is the first step toward finding relief.

Deep vein thrombosis, or DVT, is a blood clot in a deep vein. Most often occurring in the legs, these clots can also occur less commonly in the arm, under the clavicle or in the belly.

Varicose veins are abnormal branches from larger, more typical veins. Even if you don’t have one yourself, chances are you’ve seen such a swollen blue and purple bulge in someone else.
