But what Dr. Nielson is also known for is his innovative treatment for patients with hyperhidrosis (excessive sweating of the hands and face), Raynaud’s Syndrome, facial blushing and RSD. These syndromes are all connected to a hyperactive sympathetic nerve dysfunction. Micro-endoscopic thoracic sympathectomy, created by Nielson, is the least invasive surgery for people suffering from any of these ailments. This procedure has the quickest recovery time and has a high success rate for those suffering from hyperhidrosis and an 85- to 90 percent improvement rate for those suffering from Raynaud’s Syndrome.
