The best way to treat foot fungus is a combination of treatments. Foot fungus is a common skin disease caused by fungal infections, also known as tinea pedis, and can have many different types of manifestations. The treatment options for different types are also different. Foot fungus can be blistering, and in this case, antifungal creams can be applied topically, such as terbinafine hydrochloride cream or miconazole nitrate cream. Foot fungus can also be vesicular in nature, and this condition needs to be treated with astringent medication, such as a wet compress of potassium permanganate, followed by powder or oil-based medication. Foot odor can also be scaly and keratinized, which can lead to localized skin keratinization and thickening, and can be treated with ointments that soften the keratin layer, such as salicylic acid cream.
