A typical sclerotherapy session is relatively quick, lasting
only about fifteen to twenty minutes. After changing into
shorts, you will be asked to lie down on the examination table
and the skin over your spider veins will be cleaned with a topical antiseptic. Using one hand to stretch the skin taut, your doctor
or nurse will begin injecting the sclerosing agent into the affected
veins. Magnification, proper lighting, and experience all combine
to allow the procedure to be performed with precision.

Approximately one injection is administered for every group of
spider veins - anywhere from 10 to 40 injections per treatment
session. As the procedure continues, you will feel small needle
sticks and possibly a mild burning sensation. However, the
needle used is of such a small diameter, and the sclerosing solution
is so mild that pain is usually minimal.
