What Does Nail Fungus Look Like?
Nail fungus often causes the area around the base and sides of the nail to become red and irritated. At first, the edges or base of the nail is affected. As it spreads, the nail and nail bed show changes. There is often mild discomfort, itchiness, or even pain around the cuticles. Bleeding or detachment of the cuticles may occur. The nail can become discolored-yellow-green, dark yellow-brown, and sometimes white spots are seen. The nails thicken and develop abnormal grooves, lines, and tiny punched out holes. Your doctor will likely examine your nails first. To test for fungi, your doctor may scrape some debris from under your nail for analysis. The debris can be examined under a microscope or cultured in a lab to identify what is causing the infection. Other conditions, such as psoriasis, can mimic a fungal infection of the nail. Microorganisms, including yeast and bacteria, also can infect nails. Knowing the cause of your infection helps determine the best course of treatment.
