Description : What causes toenails get stuck to the flesh, to grow upward (thicken)? See detail?
Last Answer : answer:I don't know about the other two, but fungus can cause a nail to thicken. I'm not sure what you mean by upward in this case, but fungus will also raise the nail higher on the toe ... also cause toenails to turn in weird directions if they're worn too long and the nails aren't cut regularly.
