It's not likely that it's the same tick that caused your illness. Most likely it's another tick. I've heard some people can go months before it gets to the point of feeling sick. Good thing you found out though, the father of one of my sons friends had it for over a year before they could figure out what was wrong with him. They thought he was going to die he lost so much weight and was always in pain. One of my co-workers has a daughter who had it for several years before they could find out what was wrong. She would get really sick, then get better again and a few months later get really sick again.

BTW, did you know that Lyme diseased probably originated in MN?
