I had this one spot on my side show up, at first i thought it was ringworm, but the doctor ruled that out, it was small and red, now its larger and has turned more brown and it's dry around the edges. it doesn't look like eczema at all, but i have about 15 of them now showing up around my stomach, back, shoulders, arms and chest. they're small and red like the one spot was originally. What could this be?
