Our toes and toenails really are more sensitive and fragile than we realize. A small ingrown nail, a small injury, sweaty feet or unhygienic shoes can lead to infections.
I have an infected toenail right now due to injury and sweaty feet. I bruised my toe while playing sports and the side of the toenail broke off. I didn't take good care of it and I didn't change my socks frequently and now it's infected. I have to take antibiotics now, it's that bad!
