Ticks that carry diseases such as Lyme have been moving south. A woman in North Carolina experienced unusual symptoms, including blurry vision and numbness, nearly a decade ago. She saw multiple specialists and underwent various tests, but her symptoms were often attributed to anxiety or depression.

The woman's symptoms were eventually recognized as possible Lyme disease by a friend. She then requested a Lyme disease test from her primary doctor. Further details about her experience and the migration of ticks are available from NBC Los Angeles.
