Is the endovenous laser treatment for varicose vein removal painful? Dr. Luis Navarro: The procedure is done under local anesthesia and no, if the anesthesia is properly done, the patient will not feel anything. And no, you will not feel the laser inside the vein. Plus, patient is awake and you are awake in case that you have any discomfort, just let us know and we’ll put a little bit more local anesthetic.
