Eric had what is called thoracic outlet syndrome. “There’s a major vein that runs through there, and when I would raise my arm, it would pinch it and damage the vein. The clot was where it tried to heal. But it kept backing up, backing up. And like any clot, when you get enough pressure, it’s gonna blow.”
Eric took three days to recover, and then doctors took out his top rib. He rested up for the summer and hit the road again in September, never telling the public about his ordeal.
