Supermodel Christy Turlington has been diagnosed with Lyme disease, according to a U.S. report. The 38-year-old model-turned-actress is now said to be "fine" - having been successfully treated for the illness with antibiotics. A friend of the star tells the New York Daily News, "They caught it early; she's going to be fine." Lyme Arthritis, which derives from a tick bite, usually starts with some kind of rash, which starts small but can spread up to ten inches. It can cause a flu-like illness with tiredness, muscle and joint aches and a flu. Left untreated it can cause major league arthritis with joint swelling and damage your heart, and nervous system. Turlington's spokesperson assures she is fully recovered: "While we don't answer any questions about Christy's private life, so there is no misunderstanding ... Christy is very healthy and fine."
