I had all 4 taken out in one go at hospital and it really isnt that bad. Afterwards the pain really wasnt that bad at all. I could touch the sides of my face and there wasnt any pain. I had to wait in bed for a while because one socket bled a bit but after I ate something (a pot of jelly!) I was allowed home.
Tell you what going under general anaesthetic is bloody odd!! The nice man said there was going to be a scratch on the back of my hand, I had an oxygen mask over my face and the next thing I knew was this nurse shaking me awake and saying my name really loudly in me ear! I remember thinking "Oh ffs woman shut up! I'm awake! I'm awake!"
My brother had his done at the dentists and he was only sedated (that's all they're allowed to do I think). He was out of it (all wibbly) but in more pain than I was after mine.
