Depending on the method used to treat your spider veins, you may experience slight discomfort. During a sclerotherapy treatment, you may feel a slight pinch of the needle or a sting of the solution; however, the discomfort quickly subsides and is typically well-tolerated.
During laser therapy for spider veins, heat generated by the laser may be uncomfortable. Typically, a topical numbing cream is applied to lessen the discomfort.
