Yes, I'd get tested. Lyme doesn't go away by itself.
I suspect there are lots of people who are told they have 'chronic fatigue' or 'fibromyalgia' or some such syndrome (meaning a collection of symptoms without a known cause or diagnosis) who are really harboring Lyme and its evil little friends.
The word 'fibromyalgia' literally means muscle pain -- translation: "We don't know what you've got, but you say your muscles hurt, so we'll diagnose you with ... muscle pain!" Sigh.
I was one of those people who were told fibromyalgia and CFS but it's all really Lyme.
