The DeVinney family of Chatham County, North Carolina has seven members that have Lyme disease. The worst among those is Karyn DeVinney, who was forced to give up a promising college tennis career while she searched for answers to her debilitating and worsening fatigue, migraines, pain, and vertigo.
