My daughter got bit by a tick a year ago,
and in hindsight, I believe she got
Bartonella. She had an unexplained fever for a day, and then got a red rash on each of her flanks (from where the kidneys are in the back and around the side, down to the waist) with little scratch marks, about five on each side near the waist line.
The first time it showed up, she complained that it hurt and asked for acetaminophen. It was warm to the touch. It faded in a couple days.
