My son, who raced as a Cat 3 cyclist in high school has Raynauds. Being warm in your core does not stop the symptoms in your hands and feet. Just being exposed cold causes it. Generally, gloves and covering up don't help. He developed this at about age 14.It just got worse and worse. He was miserable until he researched a surgery done to correct this, that is not performed here in the mecca of medicine (Boston). My husband took him to San Antonio to the only dr. that does this. They go in through your armpit with a laser and cut one of the nerves to stop the symptoms. The surgery was originally developed for people with excessive sweating. It worked within hours. The only side effect is that he sweats a lot in his core, if he gets really hot. He only had to be in Texas for 2 days and felt good enough to go to Austin the same night as the surgery to check out Lance's town!
