The worst case of athlete's foot can be quite severe and present a range of uncomfortable symptoms. It is most commonly characterized by itchy, scaly, and red skin between the toes and on the soles of the feet. The infected area may also be sore, cracked, and blistered. In some cases, athlete’s foot can spread to other areas of the body, such as the hands, arms, legs, and torso.
The most severe cases of athlete’s foot can be painful and may include an infection of the toenail. This can cause the toenail to become discolored, thick, and brittle. In extreme cases, the nail may even fall off. The infection can also cause intense itching, burning, and stinging sensations. In severe cases, the infection can spread to the bone, leading to more serious complications.
If you suspect you may have athlete’s foot, it is important to contact your doctor right away to prevent the infection from spreading and becoming more serious.
