A nail fungal infection is a common condition of the nail that makes it brittle and discolored. It often affects the toenails. It is formally called onychomycosis. It is also so much like an athlete’s foot. Instead of infecting the skin on your feet’s bottom and the spaces in between toes, it infects the toenails.
The following are the most common symptoms of nail fungus infections: having thickened nails that can be hard to trim, brittle, and crumbly. The nail may also curl up or down and in some cases, it may separate from the nail bed. It may have a distorted shape and sometimes give off a foul smell. It may cause pain sometimes too.
