Need i go see the doctor about my ringworm?

To confirm diagnosis: A fungal infection often with ring-shaped lesion with serpentine borders and mild, flaky scales. Topical lamisil, lotrimin, or tinactin (tolnaftate) are available otc and all seem to work fine for simple ringworm on body, not scalp/bearded areas. Keep area clean, dry and apply the cream 2-3x/day should get rid of it in about 10-14 days. If not better, consult doc for possible alternate diagnosis. Good luck.
