What could this be? Athletes foot? Itchy a lot and stings a little ?

It looks like the beginnings of athletes' foot. It can be treated with an antifungal creme.

This could be either a fungal infection or athletes foot.

Fungi that infect the skin ( dermatophytes) live only in the dead, topmost layer (stratum corneum) and don't penetrate deeper. Some fungal infections cause no symptoms or produce only a small amount of irritation, scaling, and redness. .Other fungal infections cause itching, swelling, blisters and severe scaling.

Fungi usually make there home in moist areas of the body where skin surfaces meet; between the toes, in the groin, and under the breasts. Obese people are more likely to get these infections. Strangely, fungal infections on one part of the body can cause rashes on other parts of the body that are not infected. For example, a fungal infection on the foot may cause an itchy, bumpy, rash on the fingers. These eruptions (dermatophytids or id eruptions) represent allergic reactions to the fungus.

Athlete foot (ring worm) is a common fungal infection that usually appears during warm weather. Its usually caused by either Trichophyton or Epidermophyton, fungi that can grow in the warm moist areas between the toes. The fungus can produce very mild scaling without other symptoms or more severe scaling with an itchy, raw, painful rash between the toes and over the sides of the feet .Fluid-filled blisters can form.

Because the fungus may cause the skin to crack, athlete's foot can lead to bacterial infections, especially in the elderly and those who have inadequate blood flow to the feet.

oof thats an infection, you might lose your foot if you don't get it checked out.
