My wife just noticed, tonight, some small bruises on the back side of her knee. The bruises are in an ascending diagonal line running from the inside part of the rear knee joint to a couple inches up her center, rear thigh. The bruises are consecutive, small bruises. This is on her right leg. Hopefully the description is good enough. My concern is of blood clotting, since it is near the femoral artery , but I also don t know what I m taking about. :-) Anything we should be concerned with?
