What are spider veins?
Spider veins are caused by the widening (dilation) of a small group of veins near the skin’s surface. They often occur on the face and legs. They look like red or purple sunbursts or web patterns. They are more common in women.
What are varicose veins?
Varicose veins are swollen or enlarged veins. They most often appear on the thighs, the backs and fronts of the calves, or near the ankles and feet. The veins have enlarged because of a weakening or damage in the vein valves. They are found deeper in the skin than spider veins. They may be raised, bulging, or twisted. They are often blue, red, or flesh colored. If you have varicose veins, your legs may feel tired, heavy, or achy after sitting or standing for a long time. They may feel better when you put your legs up.
Varicose veins can be serious because they may be painful. They may also be linked with health problems such as:
-Phlebitis. This is inflammation of the vein.
-Thromboses. This occurs when blood clots form in the enlarged vein.
-Venous stasis ulcers. An ulcer is formed when there isn’t normal drainage in the enlarged vein.
The exact causes for varicose and spider veins are unknown. But pregnancy, heredity, obesity, standing for a long time, older age, heavy lifting, and hormonal changes may all be causes.
