A few days ago, I found 2 - 3 red circles with a red spot on the skin on both of my arms. I don't know what exactly they are, I tried researching it on the web but it keeps on telling me, it might be Ringworms but I'm not certain enough if it is ringworms though. What should I do? How do I know if it is Ringworms? What are the best course of action for a treatment? Any home remedies that might help?
