Together, spider veins and varicose veins affect approximately 80 million people in the United States each year. Spider veins are most commonly located on the face and legs. In contrast, varicose veins tend to be localized on the backside of the calf or along the inside of the leg. Although physicians do not fully understand the cause of spider and varicose veins, they do attribute factors such as genetics, weight gain, and hormonal fluctuations associated with pregnancy, birth control pills, and hormone replacement therapy, as well as sitting or standing for extended periods of time.
In addition to being unsightly, some types of spider and varicose veins can be associated with varying degrees of pain and discomfort, and in some instances, more serious medical conditions. As the most common treatment option available, sclerotherapy is a safe, effective, nearly painless procedure used to treat spider veins and varicose veins on the body.
