Schweddy’s Balls

John Schweddy is a local chef in Chapel Hill famous for his Christmas desserts, one of the most sought after being his Almond Encrusted Cinnamon Balls. He is often asked to produce them in the thousands during the Holiday season which leads to tremendous stress. John Schweddy also suffers from hyperhidrosis, a common condition in which a person sweats excessively. Commonly affected areas include the armpits and palms of the hands. John is afraid of people finding out about his condition and for that reason he refuses to shake hands with customers. This year, a new tech executive moves to town and decides to order all the Christmas desserts that John can produce. The one caveat, the executive insists on meeting John and shaking his hand. John hears about the executives wishes and decides to undergo an operation that will treat his hyperhidrosis. Unfortunately, the executive sees John before the surgery, grabs his hand, and without warning exclaims that he is so looking forward to his Schweddy’s Balls for the holidays. Which of the indicated nerves needs to be ligated to eliminate John’s hyperhidrosis?

Postscript: My compliments to SNL and Alec Baldwin for coming up with John Schweddy.

Which nerve should be ablated to eliminate sweaty palms?
