My rash began the size of a dime but expended over the next two weeks to be 7", it was not until about
the 10th day that I could see the "bulls eye" markings. Screaming red, slightly raised and not itchy, then it became red and purple/blue circles.
I also believe that this rash was not due to the original bite (looking back at my symptoms after my dx) I think I was infected about 18 months prior to this rash appearing.
Hope this helps.
