A year and a half ago, I developed a large, itchy, ring
on the back of my thigh. Because of the bulls-eye pattern, I was treated for Lyme Disease, and the rash went away. I recently developed another rash in the same area. It is more scattered this time (as opposed to ring-shaped), but it is also very itchy. Cortisone cream does not help the itch. Before this latest rash, I have also had recurring itchy spots in that area that I thought were insect bites.
