OUCH!!!!! Ginger suffers with in growing toe nails, the last time he went docs, doc said " OH I would love to take that nail off " (( he's a sadistic sod our doc )) BUT he said he would leave it a while longer, touch wood ginger hasn't suffered much with them in the last year.
Mine once fell off.... I had kicked a football wrong ( girl thing ) and it just flipped off
surprisingly though it didn't hurt.
