Hi I recently had ringworm and went to the doctor to get rid of it. I took what he have me and it went away but sometime after I noticed a ring in almost the same exact spot only this time it was different. I have looked online and can t seem to find a good conclusion it s a red ring but almost engraved in the skin and the skin inside the circle is normal skin tone except really dry/ scaly. It s not even and inch in size. It took a while but it seemed to go away on it s own. Then I noticed the same kind of spot on knee after that but gradually went away and now there is one on the back of my leg. It is sometimes a little itchy but doesn t bother me otherwise. What could it be ?
