Sounds the same as they all had here. The rash mine had lasted a few weeks from memory & kind of looked like lace on their legs & bellies.
Can't remember if it started like that or not. They were fine, no reall issues with it, but hope that you don't get it. My friend picked it up from her DS & the symptoms are so much worse in adults, including headaches & bad aching joints. She couldn't cope & had to go stay with her mum for 2 days.
