Personally, I hate feet. They're ugly, they usually smell bad, and they're highly prone to fungal infections. And unfortunately, since (in my opinion) feet and toenails are already ugly it can be difficult to recognize the signs of a fungal infection.

Here are the major things to look for, according to the American College of Foot and Ankle Orthopedics and Medicine: yellow or discolored toenails, extra thick toenails that are hard to cut, crumbling toenails, or (I would hope this problem is obvious!) nails that have separated from the nail bed.

Happy examining!
