Yeah, I looked up some ringworm photos and they looked like mine, so it may very well be...still those two marks at the center...and the tiny blisters... Bythc recommended something that works for both so that'll work well. Luckily it seems to be drying out now (getting sort of flaky) and hasn't grown in size. Thank you very much, your comment was really helpful and I'm glad I went through the trouble of adding the photo!
