Hi,
This sounds like a fungal infection of the skin.It causes itching or a burning sensation in the groin area, thigh skin folds.
Affected areas may appear red, tan, or brown, with flaking, peeling, or cracking skin.The border may exhibit tiny pimples or even pustules, with central areas that are reddish and dry with small scales.
Anti-fungal agents containing tolnaftate, clotrimazole or miconazoleavailable as can be applied on the affected areas twice a day.
To cure the infection naturally, keep moist and warm areas of the body clean and dry.
Powders with menthol or zinc oxide may be used, like Gold Bond medicated powder, to soothe the itch.
Tea tree oil can also be used since it is a natural anti-fungal.
