Ann Jones tried everything short of surgery for her chronic migraines, which have plagued her since she was a child.
"They've actually gotten worse in my old age," says Jones, who is 70 years old and lives in Tucson, Ariz.
Jones would have as many as two dozen migraines a month.
Over the years, some treatments might work initially, but the effects would prove temporary. Other medications had such severe side effects she couldn't stay on them.
