Oh poor little Hank!!
These things do happen. It's not your fault.
Kittens are always climbing and making mishief.
The crate is a good idea it will make him rest and there fore the swelling will go down.
If he's watching you and crying to get out maybe pop him and the crate in another room part of the time and then he might get bored and sleep more.
Lets us all know how he gets on.
Good look for Monday.
