Tongue tied babies

So I got my sons tongue cut today because he was not latching and I had to pump and my supply went down a lot. How long does it take for them to feel better? I know only a week for it to fully heal about but when does it stop hurting? I just feel so horrible I want to cuddle and hug him non stop! Which is what I'm doing and nursing a lot. Just need some reassurance that this is best for him.
