Answers to Common Questions About Foot and Ankle Sports Injuries

There are various reasons toenails become yellow, but the most likely explanation is a case of nail fungus (onychomycosis). Fungal infections in the toenails are, unfortunately, fairly common. The responsible fungi are microscopic—so you cannot see them and know to avoid the tiny spores—and typically reside in warm, damp areas, including places where people normally walk barefoot (such as indoor pool decks, gym locker room floors, and communal showering areas). 

Toenail fungus is a stubborn infection, one that usually requires professional treatment. For optimal results, it is best to come in and see us at the earliest opportunity (when the infection is most easily treated). Left unaddressed, this problem will only continue to worsen. 

Beyond a fungal infection, other potential causes of yellow toenails include diabetes, tuberculosis, bronchiectasis, jaundice, psoriasis, and thyroid problems. In some cases, toenails become yellowed simply due to natural aging processes. There is also an extremely rare genetic disorder known as “yellow nail syndrome,” which can present in conjunction with lymphedema. 

As with any part of the body, feet can itch for a variety of different reasons. The most common explanation is a case of athlete’s foot. This is a fungal infection that can start between toes and then spread across the foot. There is usually a noticeable redness and the itching or burning sensation is usually strongest after taking off shoes and socks. 

Whereas an itchy foot is often athlete’s foot, there are other possible explanations. Eczema, psoriasis, and skin allergies. With regard to potential allergens, sometimes the dyes used in socks and shoes—or even the detergent used to wash them—can be responsible for an allergic reaction.
