Varicose (VAR-i-kos) veins are swollen, twisted veins that you can see just under the surface of the skin. These veins usually occur in the legs; however, they can also form in other parts of your body. Varicose veins are a common condition, and usually cause few signs or symptoms. In some cases, varicose veins may cause complications, such as mild to moderate pain, blood clots, or skin ulcers.
A number of vein problems are related to varicose veins, such as telangiectasias (tel-AN-juh-ek-TA-ze-uhs), spider veins, varicoceles (VAR-i-ko-seals), and other vein problems.
Telangiectasias are small clusters of blood vessels. They’re usually found on the upper body, including the face.
These blood vessels appear red. They may form during pregnancy and often are found in people who have certain genetic disorders, viral infections, or other medical conditions, such as liver disease.
Because telangiectasias can be a sign of a more serious condition, see your doctor if you think you have them.
Spider veins are a smaller version of varicose veins and a less serious type of telangiectasias. Spider veins involve the capillaries, the smallest blood vessels in the body.
Spider veins often show up on the legs and face. They usually look like a spider web or tree branch and can be red or blue. They usually aren’t a medical concern.
