Jock itch?

I have red, itchy lesion on my upper thighs in the groin aea. My dermatologist said it was a "tropical" (I live in Florida part of the year) fungal infection, and gave it a two-barreled latin name which I forgot. He prescribed Vytone 1% cream. Is there a better or cheaper alternative? A generic drug that will effect a cure I have been using a combination corisone cream and anti-bacterial cream together but they have not prevented renewed flare-ups.

Hi,
Tinea cruris is the scientific name for fungal infection of the groin region. Official alternative names include jock itch.

It may involve the inner thighs and genital areas, as well as extending back to the perineum and perianal areas. Affected areas may appear red, tan, or brown, with flaking, rippling, peeling, or cracking skin. It may cause itching or a burning sensation in the groin area, thigh skin folds, or anus.

A warm, damp environment allows the fungus to cultivate in these areas, especially with tight, sweaty or rubbing clothing aggravating the rash.
It is best treated with antifungal creams containing tolnaftate, clotrimazole or miconazole  applied on the rash. If the skin inflammation causes discomfort and itching, glucocorticoid steroids may be combined with the anti-fungal drug.

To cure the infection naturally, keep moist and warm areas of the body clean and dry by using talcum powder. You can use anti-dandruff shampoos on the infected skin as many contain anti-fungal chemical compounds such as pyrithione zinc, selenium sulfide, and ketoconazole (Nizoral). Tea tree oil can also be used since it is a natural anti-fungal.

Most fungal infections are known to recur when they have the right atmosphere to thrive in.
