I had this outpatient surgery about three years ago. I waited a long time to finally do it. I had a lot of pain and trouble making a fist. I took off three weeks of work. I could have gone back after about ten days. I had to go back after a week to get the stitches removed and then a few days after I was able to fly.
I do not recommend slamming a book on it. I did that once and it did come back bigger and more painful.
