re: Jacked up toenails

You're probably going to lose that nail. I did that once--damaged my toe nail hiking in crappy boots. It turned black, eventually fell off, then grew back.

But I'd see a podiatrist just in case. If it's fungal too, he should be able to prescribe some kind of anti-fungus meds. Warning: they'll probably be ridiculously expensive (at least they were when my mom was on them).
