What are the usualy signs of ringworm, and how does it go away?

Ring-like rash. Ringworm is called this because it classically forms a raised ring of scale and mile redness. Often the center part of the ring is clear, or relatively clear. However, it does't always look this classic. Ringworm needs to be treated with an anti-fungal medicine. Topical or systemic meds can both work. It can be easy to diagnose so if in doubt you should be seen.
