I've had it three times as a kid and the most recent one didn't produce a "bulls eye" rash. I knew what it was by then and went to the doctor, symptomatic, telling them that I had limes, but they hadn't seen it before and told me I had the flu.
I got a second opinion with blood work that came back positive for limes.
So if you have "the flu" symptoms around a time you were had been running around grassy area where limes is a thing, ask for blood work.
