Varicose veins are swollen and enlarged veins that usually occur on the legs and feet. They are often lumpy, bulging or twisted in appearance. Other symptoms include: aching, heavy and uncomfortable legs, swollen feet and ankles.The exact cause of this unwanted “body art” is not known, but a genetic tendency toward weak, vein valves plays a big role. Hormones also play a part, accounting for the increased incidence in women. Puberty, pregnancy (pregnant women are very prone), and menopause, as well as taking estrogen, progesterone, and birth control pills, can weaken vein valves and change leg circulation.Superficial varicose veins normally do not require medical attention, but they should not be ignored. To relieve the discomfort, your doctor may recommend the following:Elastic support stockings, which you can buy in most pharmacies and medical supply stores. Support stockings help your leg muscles push blood upward by concentrating pressure near the ankles. Put them on before you get out of bed in the morning. Raise your legs in the air and pull the stockings on evenly; they should not feel tight in the calf or groin. You should wear them all day and also elevate your legs for 10-15 minutes several times throughout the day.Over-the-counter anti-inflammatory drug such as aspirin or ibuprofen to alleviate occasional swelling and pain can also be used. Other forms of treatment include Laser therapy and surgical removal.
