What do you do when you stub your toe?

because there's not much muscle or fat to help soften the pain, thus causing the toe to be a very sensitive part of our bodies.

Also, because, like the fingers, the toe has many nerve endings so is very sensitive to any touch, never mind pain.

On top of this, if you consider the reasonably high speed that the foot is travelling at and the small, fragile shape of the toe, it is logical that this would cause a decent amount of pain. Or your mum might have bitten it during the night.
