Why Do You Get Spider Veins?

Spider veins are more common in people exposed to long periods of standing or sitting, and in those who experience hormonal changes, as well as due to genetics.

What to Expect During Sclerotherapy?

The procedure of sclerotherapy involves injecting a medication known as sclerosant into the spider veins.

The sclerosant solutions work by irritating the lining of the veins, which causes scarring and inflammation that eventually lead to the closure of the vein.
