Had mine removed last year in January. As a 22 year old I was told the pain is less intense if the tonsillectomy/adenoidectomy is done as a child.
It hurt. I won't lie; it really hurt consistently for 3 weeks.
The doctor will tell you to make sure he is drinking water. There are PLENTY of days where even water made me break down crying.
Stay on top of the pain medication. Pain is easier to prevent than it is to control once it's gotten out of control.
I got to this question by clicking "Sierra Vista" so if you are in SV, know that the surgical staff at Sierra Vista Regional is top notch. They were very kind, very gentle with the IV catheter and sweet as pie with the recovery.
Waking up from anesthesia is hard, hard, hard. It's like trying to wake up but someone has taped your eyes shut. It takes a full day to shake off the effects and it isn't easy when your throat hurts.
Just go slow. Stock up now on popsicles! They say jello, but there was no way I was going to eat Jello...WAY too painful even at week 2 and 3.
