Yep, wisdom extraction is traumatic, like any moderate to major surgery, especially if there are stitches.
When I had mine out (all four at once) one of them was impacted sideways so severely they had to break my jaw and section that fucker out. Said they scraped all this bacteria off the jaw while they were in there. I projectile vomited blood when I woke up, because the second wasn't that proficient with the suction, until they injected me with Compazine. mmmmmmmm
Then they gave me Synalgous, a very nice synthetic barbituate, and I watched old Twilight Zone reruns blown out of my mind for the next week or so.
In retrospect, it was still the most horrible experience of my life.
