Ticks that cause diseases like Lyme are moving south, raising concerns about doctor preparedness. A woman in North Carolina experienced bizarre symptoms, including blurry vision and numbness, nearly a decade ago. She saw multiple specialists and underwent various tests, but her symptoms were often dismissed as anxiety or depression.

The woman's symptoms were eventually recognized as possible Lyme disease by a friend, leading her to request a test from her primary doctor. Further details about her experience and the migration of ticks are available from the source. Limited information is available on the impact of this migration in the San Francisco area, but the source provides more information on the woman's story and the issue of tick migration.
