Yep had my four extracted like that. I had to go under a general in the hospital they were such a mess since I'd wimped out on having them extracted for years.

He needs to avoid having his head lower than his heart, strenuous exercise, that sort of thing. I managed to pop all the stitching on both bottom extractions because I decided I just HAD to hand wash a darned floor the day after surgery (yes I am an idiot on occasion though that time I think it was the pain meds LOL). Also no hot or cold foods or gawd help him anything crunchy until he's fully healed.
