How is ringworm diagnosed?
Often, the diagnosis of ringworm is obvious from its location and appearance. Otherwise, skin scrapings for microscopic examination and a culture of the affected skin can establish the diagnosis of ringworm. If the diagnosis is unclear, a potassium hydroxide (KOH) preparation of a skin scraping can be reviewed under the microscope to confirm the diagnosis of a fungal dermatophyte infection. If a dermatophyte infection is present and the skin problem is misdiagnosed, inappropriate treatment might be prescribed that could actually worsen the infection.
What is the treatment for ringworm? Are there home remedies?
Home remedies cannot cure ringworm. To cure ringworm, it is necessary to take antifungal medications. Ringworm can be treated topically (with external applications) or systemically (for example, with oral medications):
Topical treatment: When fungus affects the skin of the body or the groin, many antifungal creams can clear the condition in around two weeks. Examples of such preparations include those that contain clotrimazole (Cruex cream, Desenex cream, Lotrimin cream, lotion, and solution), miconazole (Monistat-Derm cream), ketoconazole (Nizoral cream), econazole (Spectazole), naftifine (Naftin), and terbinafine (Lamisil cream and solution). These treatments are effective for many cases of foot fungus as well. Many of these antifungal creams are available as over-the-counter preparations. It is usually necessary to use topical medications for at least two weeks.

Systemic treatment: Some fungal infections do not respond well to external applications. Examples include scalp fungus and fungus of the nails. To penetrate these areas and in cases of particularly severe or extensive disease, oral medications can be used.
For a long time, the only effective antifungal tablet was griseofulvin (Fulvicin, Grifulvin, and Gris-PEG). Now, other agents are available that are both safer and more effective. These include terbinafine, itraconazole (Sporanox), and fluconazole (Diflucan). Oral medications are usually given for a three-month course.
