Yesterday I noticed several small unknown bug bites on my upper left thigh (near my butt). Today, after I got out of the shower (because it was itching in the shower), I noticed now there is a deep purple spotty/blotchy rash in the same spot as the bites. It is the size of like a baseball. If you see the attached picture, it looks like that except a little more clustered and there are more, but not many more. Also, the purple spots are flat. The bug bites are obviously raised, but the spots themselves are flat. And again, it is only on my upper left thigh, no where else on my body.
