Millions of women and men are bothered by spider veins – those small yet unsightly clusters or sunbursts of red, blue or purple veins that most commonly appear on the thighs, calves and ankles. In fact, it’s estimated that at least half of the adult female population is plagued with this common cosmetic problem. Although generally not a health risk alone, patients can be symptomatic with itching, burning, or achiness. Many factors including pregnancy, hereditary factors, trauma and hormonal changes contribute to the formation of varicose and spider veins.
