Sclerotherapy
Sclerotherapy, involving the injection of a solution (that is a sclerosant) with a miniscule needle, is a treatment designed to alleviate or eliminate cosmetically undesirable spider veins and varicose veins. The sclerosing solution serves to aggravate the veins' inner wall until this lining expands and hardens. Eventually, the treated area will be absorbed into the surrounding bodily tissue. A slight amount of irritation may be felt during the procedure, along with a feeling of pressure for minutes upon the injection of the more prominent veins.
