A vein doctor is a physician who specializes in diagnosing and treating conditions that affect blood flow in the veins, most commonly in the legs.
Patients often search for a vein doctor near them when they notice symptoms such as leg pain, swelling, heaviness, visible veins, or skin changes.
This page explains what a vein doctor does, when it makes sense to see one, and how a vein specialist helps determine whether treatment is needed.
If you’re experiencing leg symptoms or visible veins and are unsure who to see, a vein evaluation can help clarify whether a vein specialist is appropriate.
