10 Signs of Deep Vein Thrombosis

6. Visible or Bulging Veins

Although it doesn't occur in everyone, visible or bulging veins may be a telltale sign of deep vein thrombosis. When a clot is present, blood is not able to flow as easily and may cause the vein the enlarge. If the tissues in your leg are swollen, it may be difficult to see whether the vein itself is swollen. However, some patients do experience this on its own. Having consistently visible veins, including varicose veins, may be a sign that you are at higher risk for developing DVT, as well.
