FYI,
the classic sign is the "bullseye" around the bite. However, this does not always appear. A fever that breaks on its own without tylenol, then goes back up, etc.. is pretty much a surety that you have it. Also, you can get bit by twenty deer ticks and not get lyme. They must first bite a deer that has it, which is a toss up if the deer has it, and then they must bite you once they are infected. I've had it twice, and both times caught it within a week so I got it cured. And I've found countless deer ticks on me.
