Sclerotherapy is performed as an outpatient procedure in the office without local anesthesia. The area to be treated will be cleansed with antibacterial agents and the injections will be performed. Most patients experience a sensation similar to a pinch or "mosquito bite." Occasionally, a mild burning sensation is felt during the injection, but this subsides quickly.

Most treatments require 15 to 25 minutes after which, compression dressings will be placed on the injection sites. You, then, will be asked to put on the support stockings you were instructed to bring with you. The dressings are worn until the next morning and the support hose are worn for at least 2 more weeks. One must avoid exercise for at least 24 hours. Discomfort during this period is minimal to non-existent. Mild bruising may be seen around the treatment sites. While there are remote risks of other side effects that will be explained at the time of your initial consultation, these risks are rare when the procedure is performed by an experienced physician.

The number of treatments will vary according to your condition. The first treatment at the time of your initial consultation involves a small test area. If this injection is well tolerated, then subsequent treatments can be initiated. Most patients require 2-3 treatment sessions; however, the exact number cannot be predicted.

Veins eliminated by sclerotherapy do not return. Sclerotherapy does not, however, prevent the formation of new veins. Most patients will develop new veins over time and this should not be mistaken as a return of the original blood vessel.
