Toenail fungus, also called onychomycosis, is a common fungal infection of your toenail. The most noticeable symptom is a white, brown, or yellow discoloration of one or more of your toenails. It may spread and cause the nails to thicken or crack. Sandal season or not, toenail fungus typically isn’t what you want to see when you look at your feet. Luckily there are many treatments you can try.
Diagnosis is made based on clinical exam and can be confirmed by viewing scrapings of the nail under a microscope, or growing the fungus in a culture medium. This is not an easy condition to cure, so rather than trying home treatment with over-the-counter medications, it's best to see your doctor. As with many conditions, nail fungus infections are easier to treat if you catch them early.
If the fungal nail infection is severe, tablets can be used in combination with nail polish or cream. For example, if the nail is very thick, urea cream can be used (in addition to taking tablets) to gradually remove or partially file off the affected nail. Combining these treatments may also be an option if there are large collections of fungi beneath the nail. Another option for severe fungal nail infections is professional medical footcare. If the nail is filed off, it’s important to ensure good hygiene and disinfect the area, because the removed nail tissue could contain infectious fungal spores.
