I have 4 year old triplets and two of them had enlarged adenoids. We had them removed about 6 months ago. My boys did great and they did not have any pain after the surgery. They were up and running that afternoon. One of my sons they said complained of some pain in the recovery room (before I got to see him) so they gave him some pain meds for that. It took him a little longer to wake up and to get back to normal but he was fine by the time we left the hospital. The other one did not require the extra pain meds and was bouncing out of the hospital bed as soon as he woke up!
Good luck with the surgery!
