I blackened the toenail on my big toe during a marathon a few months ago, and now, finally, its falling off. I figured there'd be a new one underneath, but not so. Aside from the queasy feeling, I'm wondering if I can get an infection or something without it. And how long will it take for a new one to grow in? Anything I should do to treat it?
I'm not digging this nasty scene. Thanks in advance for any comments.
