What is sclerotherapy?
Sclerotherapy is a treatment to get rid of varicose veins and spider veins. A chemical called a sclerosant is injected into the vein. This causes the vein to close.
The procedure may cause some pain. The chemical may cause burning or cramping for a few minutes at the injection site.
The procedure may take about 15 to 60 minutes. It depends on how many veins are treated and how big they are. You should be able to walk on your own after the treatment.
