Hi there Bloom!

When I was a kid I had multiple sets of grommets inserted until the age of 12! For the same problem! Except I also suffered bad ear aches..

I remember being fine after the surgeries except for being a bit groggy from the anesthetic there was no pain or anything...

It's a pretty easy surgery and there is no damage to the ear at all so he should not have any pain afterwards!

He should bounce back pretty quickly

Good luck x
