An antifungal over the counter cream should work. i used that when i had it and it went away.
Treatment

Some infections disappear without treatment. Others respond to such topical antifungal medications as naftifine (Caldesene Medicated Powder) or tinactin (Desenex) or to griseofulvin (Fulvicin), which is taken by mouth. Medications should be continued for two weeks after lesions disappear.

A person with body ringworm should wear loose clothing and check daily for raw, open sores. Wet dressings applied to moist sores two or three times a day can lessen inflammation and loosen scales. The doctor may suggest placing special pads between folds of infected skin, and anything the person has touched or worn should be sterilized in boiling water.

Infected nails should be cut short and straight and carefully cleared of dead cells with an emery board.

People with jock itch should:

* wear cotton underwear and change it more than once a day

* keep the infected area dry

* apply antifungal ointment over a thin film of antifungal powder

Shampoo containing selenium sulfide can help prevent spread of scalp ringworm, but prescription shampoo or oral medication is usually needed to cure the infection.

Alternative Treatment

The fungal infection ringworm can be treated with homeopathic remedies. Among the homeopathic remedies recommended are:

* sepia for brown, scaly patches

* tellurium for prominent, well-defined, reddish sores

* graphites for thick scales or heavy discharge

* sulfur for excessive itching

Topical applications of antifungal herbs and essential oils also can help resolve ringworm. Tea tree oil (Melaleuca spp.), thuja (Thuja occidentalis), and lavender (Lavandula officinalis) are the most common. Two drops of essential oil in 0.25 oz (7 ml) of carrier oil is the dose recommended for topical application. Essential oils should not be applied to the skin undiluted. Botanical medicine can be taken internally to enhance the body's immune response. A person must be susceptible to exhibit this overgrowth of fungus on the skin. Echinacea (Echinacea spp.) and astragalus (Astragalus membranaceus) are the two most common immune-enhancing herbs. A well-balanced diet, including protein, complex carbohydrates, fresh fruits and vegetables, and good quality fats, is also important in maintaining optimal immune function.
