Broken Bones?
Ow omg that sounds painful. Just looking at my own nails I wonder how they actually stay on.
Think about it... It is just skin underneath, and it is barely "connected" to the nail really
(at the base it is) but it grows to hang off ones finger tips.
How Is the skin natural glued to them? Lol anyway...
I am pretty sure it will grow back!, but it depends on additional damage.
My mom slammed her thumb in a car door when she was a teenager, and lost her thumbnail. But now her thumbnail grows with a raided line across it (parallel to her finger). That is only because she broke the bone.
So as long as she did not brake her toe, it should be ok.
But if you are not sure, maybe get an X-ray to see what you should do to help it heal properly.
Hope this was helpful 🙂 !
