Tenderness
The skin directly above the clot and surrounding areas can also become tender. This is despite the fact that blood clots tend to form deep in the legs with no sign of bruising on the surface of the skin. The tenderness can cause the veins under the skin (near or on the affected area) to become visible although this occurs after the blood clot has become relatively large in size.
The tenderness can affect both legs even if the blood clot affects one leg only. This is usually the case because people tend to overuse their stronger leg. This subconscious decision can cause joint and muscle strain which is manifested as pain and tenderness.
