Ive had it for a like a.month now. The mark used to itch but not anymore. And now Im getting marks.on my arms that itch and my arms are also seriously dry around the arms. My shins have been super itchy as well but there arent any visible marks and idk whats happening. I cant explain it..I think it may be ringworm but only the mark Ivebhad for a month now looks even remotely similar. Please somebody tell me, what is this?
