NASCAR racing driver Trevor Bayne has been diagnosed with multiple sclerosis. The 22 year old reveals doctors discovered he was suffering from the autoimmune condition in 2011, the same year he made history by becoming the youngest winner of the Daytona 500, after he was hospitalised for an "inflammatory condition" that left him feeling nauseous and fatigued. But Bayne, whose younger sister also suffers with MS, insists he is currently showing no signs of the potentially debilitating disease and plans to compete in this weekend's Homestead-Miami Speedway race in Florida as scheduled. A statement released by Bayne reads: "There are currently no symptoms and I'm committed to continuing to take the best care of my body as possible. As for now, I want to close out the season strong this weekend at Homestead and then shift my focus on getting ready to compete for the NASCAR Nationwide Series Championship in 2014."
