Superficial Vein Thrombosis
A superficial vein is a vein which is close to the surface of the body. They are normally responsible for helping to cool the body. It may be possible to see these veins bulging out under certain conditions. Patients may feel a slightly harder area or witness some reddening of the area. These thromboses are not normally as serious as deep vein thrombosis; however they can become more serious if they are able to enter deep veins through the perforator veins.
