Varicose Veins is a chronic and recurrent condition.  The variety of treatments available will not offer a cure, but will help to control the condition. Sclerotherapy involves injecting special medication called sclerosing agent to directly inject into your varicose veins. This causes an irritation of the inner lining of the vein resulting in closure of the vein. A small gauge needle is used to perform the injections and most patients report minimal discomfort. Many people who have had sclerotherapy performed have satisfying results.
