The Sclerotherapy Procedure
Sclerotherapy is performed by a specialist nurse who has been trained in Sclerotherapy and the procedure itself takes approximately 15 to 30 minutes. The number of veins injected in one session varies, and depends on the size and location of the veins, as well as your general medical condition.
The injection is usually a salt solution which is injected through a very fine needle directly into the vein. At this point, you may experience mild discomfort and cramping for one to two minutes, especially when larger veins are injected.
