Cat lost full nail

Hi,

My cat lost his full nail a day ago, we chatted with the vet and got some pain meds for him, I was looking at his nail today and it’s kinda crusty and a little stuck to his other nail/“toe”.

Anybody know if this is normal? He’s not licking it at all, using his foot to scratch his head like normal, running around and playing, eating normal.

Edit: He has his full wick, it was basically just the hard nail part that fully ripped/fell off
