How can you identify a nail fungal infection?

Identifying a nail fungal infection typically involves looking for specific symptoms that differentiate it from other conditions affecting the nails. Discoloration and thickening of the nails are hallmark signs of a fungal infection. The color may vary, often appearing yellow or brown, while thickening usually occurs as the infection progresses, leading to changes in the overall nail texture and structure. This symptomatology is key in determining the presence of a fungal infection, as it directly relates to how fungi affect the composition and appearance of the nail.

Other symptoms may occur with different types of nail conditions or infections, but they do not precisely indicate a fungal infection. Redness and swelling can signal an inflammatory response to various issues, peeling and dryness are more commonly associated with other skin conditions or environmental damage, and itching and pain could relate to several dermatological issues, including allergic reactions or irritations. Thus, focusing on discoloration and thickening provides a clearer identification of a nail fungal infection.
