Q: It looks like I have fungus beneath my toenail, but how can I be sure? Does toenail fungus go away on its own? Experts say these infections don’t go away on their own and can easily spread from person to person without treatment. “Fungus tends to be greedy,” said Dr. Boni Elewski, chair of the department of dermatology at the University of Alabama at Birmingham. Toenail fungus affects an estimated one in 10 people worldwide, and becomes more common with age — afflicting more than half of those ages 70 and up.
