One of my best friends has Lyme and it wasn't caught for 1 1/2 and it's been quite serious. There is no predicting the course of this disease: some clear up with antibiotics, some with other treatments, sometimes it goes into remission, sometimes it doesn't go away, and sometimes it goes away when there's no clear explanation due to timing or treatment.
My friend found that she has to limit her time at the Lyme sites because it is so depressing and opinions are so strong as to what helps/what doesn't. As you've probably seen treatments range from convention medicine all the way to some alternative many of us would think are pretty far out there. Visit the doctor, do your research, choose a course, dose liberally with prayer (or whatever) and go with it. I know it's heartwrenching not to have firm answers but very little is know.
This would be a good time to mention to people that any time you have an unexplained rash, take a picture even if you don't get it checked out. Many doctors won't even recognize the rash. And anyone who has unexplained neurological symptoms should have complete blood work done including for Lyme. My friend's never had a rash.
