I have a red blotch appear on the upper inside of my leg about the size of a quarter, then smaller ones appeared around the large one and spread to my other thigh. I do not have anywhere on my back, stomach , arm etc. only on my upper thigh in and around. darker red outer circle, look scaly and itchy somewhat. went to a dr & said it might be ringworm, given meds, but no improvement. used nail polish, tea tree oil, cortisones and many other things but still not gone. I ve had for about 2 months now.
