pre-surgery I never thought Tylenol did much for me, but actually, it does. I mostly take it for headaches, but oddly, I rarely get them anymore.
I had pretty much zero pain after surgery. They sent me home with pain meds which I never even bothered to open. I think I might have taken Tylenol the first couple of days, though (I can't really remember since it's been a few years). Pain with these surgeries is really across the board - some people have none, some people have a lot. Most people seem to have little to none, though. But if you're one of the unfortunate ones who has pain with this surgery, you'll have the pain meds - just take them as directed to keep on top of it, and it should be pretty manageable.
