There are several general conditions of redness on the soles of the feet, the most common of which may be due to a fungal infection on the soles of the feet, or flushing due to eczema on the soles of the feet. Some people develop localized sweat irritation due to excessive sweating of the feet, eventually forming large patches of erythema on the bottom of the feet, some may be accompanied by varying degrees of itching, and some may even experience painful symptoms. But there is another type of erythema appearing on the bottom of the feet, which is erythema keratosis, and erythema keratosis is not only erythema appearing on the bottom of the feet, but may also appear on the palms of the hands. This erythema may be erythema on the basis of keratosis, and it is hereditary and symmetrical. For this disease there are usually no obvious signs of remission, and even if treated there is only temporary relief. However, erythema that forms due to eczema or fungal infection is usually still treatable.
