(HealthDay News) -- Varicose veins, also known as spider veins, look dark blue or purple under the skin. They may also appear as twisted clumps of veins that may cause the skin above them to harden and swell.
Although many people with varicose veins don't have any other symptoms, the Cleveland Clinic says that some people may have swelling or pain in the legs, itching, soreness or aching. Some skin discoloration may also occur.
Varicose veins occur most often among women, and may be influenced by a number of factors. Being older, overweight, and having a job that requires standing all day may contribute to varicose veins. Other factors may be heredity, crossing the legs often, using birth control pills, or use of post-menopausal hormone therapies.
Treatment may not be necessary, according to the clinic, unless you are experiencing pain. Support hose may help reduce symptoms in some people, and lifestyle changes like losing weight, exercise, and getting off your feet may also help.
