I have several heart shaped rashes on my arms and one on my stomach. i've tried all kinds of ringworm creams assuming that's what it is. left scars?

Hard to say: A common truism about treatment is when appropriate measures don't fix a problem the diagnosis is likely wrong. Skin rashes can represent infections, local reactions,allergies or systemic illness. Diagnosis is often easy when seen by a trained observer. If your treatment for ringworm isn't working it is likely not ringworm. To find out what it is and treatment options will need a visit.
