The treatment area will be sterilized, then the nurse injector will begin injecting the solution into first the larger veins, then smaller ones, monitoring the progress of the chemical throughout the process. For every inch of vein treated, one injection will likely be administered. Since the injection needle is so small, patients often feel little pain and do not need any anesthesia. The injection process typically is complete in just 15 to 30 minutes. A minor stinging or burning sensation is common during and right after the injections are made, but is short lived. After the treatment is finished, a bandage will be applied.
Large varicose veins are not treated with sclerotherapy, because they require too much solution to be injected than is safe. Small to medium sized veins respond best to sclerotherapy procedures.
The number of sessions required depends on the depth, number, and size of the veins being treated. While some patients are happy with the results after just one treatment, others may desire further injections for the optimal effect. These follow up treatments should be spaced at least four weeks apart so that the effects of the previous treatment can be accurately evaluated before injecting more.
There is essentially no recovery period associated with sclerotherapy for varicose veins. You can immediately walk afterward though you shouldn’t plan on any vigorous physical activities or exercise. Just take it easy for a few days, and avoid sun exposure to the area for some time. As mentioned, you’ll likely want to wear compression stockings for a periodof timeto ensure regular pressure is maintained surrounding the treated veins.
