1, see if your soles are particularly red and feel hot. As red as being beaten. This is blood fever, no problem. Lack of vitamin C. Blood heat can cause skin exposure.

2, the soles of the feet itch, you touch it carefully, especially where there are small peas. This needs to be touched, because it is difficult to see in the early stage. Red peas and white peas. If you needle it, water will flow out. And there will be more and more, and the seam between the sole and toe is the most itchy place. Toes itch and itch. If so, I will tell you that this is not a serious illness, but a precursor to beriberi. Wash with washing powder or soap. Don't wait for the wound to break or the exposed skin to fester before washing. Don't wear shoes that are too hot or too tight. If it is sweaty feet, wrap a circle of toilet paper on your toes to absorb sweat before wearing shoes.

If you still can't solve your problem, you can go to the hospital.
