There are three major risks associated with sclerotherapy by injection. The first risk is not injecting in the vein and injecting outside of the vein and there being no effect, no treatment at all. The second complication is injecting too superficially, injecting above the vein, and you can have some skin or tissue necrosis, localized loss of skin in that area. This usually heals fine, though. The third complication is when you do inject sometimes you can get hyperpigmentation or darkening of that area surrounding the spider veins. In general, when the injection is performed the legs usually look worse for about two weeks and then start to look better.
