Venous Obstruction

Venous obstruction happens when blood flow through a vein is blocked or slowed down. Veins carry blood from your body back to your heart, but if something blocks that flow, it can cause problems. The blockage could be due to a blood clot, scar tissue, or compression (like something pressing on the vein).

When blood can’t flow properly, it can lead to swelling, pain, and visible veins in the affected area—usually in the legs.
