Many 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 they develop in people who have certain genetic disorders, viral infections, or other 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 appear on the legs and face. They're red or blue and usually look like a spider web or tree branch. These veins usually aren't a medical concern.
Varicoceles are varicose veins in the scrotum (the skin over the testicles). Varicoceles may be linked to male infertility. If you think you have varicoceles, see your doctor.
Other Related Vein Problems
Other types of varicose veins include venous lakes, reticular veins, and hemorrhoids. Venous lakes are varicose veins that appear on the face and neck. Reticular veins are flat blue veins often seen behind the knees. Hemorrhoids are varicose veins in and around the anus.
