All patients are instructed to walk in the days following the procedure so that blood will circulate through healthy veins.  Compressing the treated vessels by wearing prescription support hosiery is also recommended to maximize the treatment results.  You may note a brownish discoloration following the course of the treatment.  Normally, this discoloration will be absorbed within a few weeks.  Tiny ulcerations at the injection site have rarely been noted.  Although they are somewhat painful and slow to heal, they pose no health risk.  Avoidance of sun exposure until the areas are healed is recommended.  You may return to work after the treatment is done.
