Oh my goodness! This must have been an awful experience for you. I don't know much about ringworms, but on Wikipedia it says:
"Topical antifungal drugs containing miconazole and clotrimazole, available by prescription or over the counter, are used to clear up the infection. A folk remedy for ringworm is a 1:1 solution of cider vinegar and water. Another alternative is 2 drops Tea Tree Oil (Melaleuca Oil) mixed with an ounce of water. In cats and cattle, sulfurated lime rinses are often used to treat ringworm. Enilconazole, as a rinse, is an effective ringworm treatment available in many countries for treating animals. Fungal infections may take a while to clear up. Terbinafine is highly effective for Tinea corporis. It treats itching, burning, cracking, and scaling that accompany this condition. It cures most ringworm except the types affecting the nails or scalp, which are very difficult to treat.
Griseofulvin is a traditional drug used to treat ringworm in both animals and People. It can be very effective, but may produce side effects.
Undecylenic acid (Castor oil derivative) is an effective fungicide for fungal skin infections such as ringworm."
