I have to jump in here as an adult who just had this procedure in December - PLEASE DO NOT BE AFRAID AND JUST DO IT!! your child will thank you, and not even realize it
I did a lot of reading, etc before my surgery and apprantly the rumors are true, it is worse when you are an adult. For some reason, they way the throat developes at some point between the ages of 12 and 16 this goes from being a simple procedure to PURE PAIN!!! It was horrible, I could not eat, talk, sleep, anything for 2 weeks. It was week 3 before I attempted work and that was only half days. I have given birth and would do that again before a tonsilectomy any day. In fact my joke is that if they grew back tomorrow they would stay in - it was that bad.
Now, that being said, my cousins kid got hers out the same week. She is 5. She was eating cheeseburgers the next day!! (Oh the thought of the ketchup and pickles on those wounds still makes my skin crawl - but it did not bother her a bit). She healed up way faster than I did and was not in nearly as much pain as I was. (Oh, I would like to quickly add that I took very good care of my wounds, I drank lots of water, with no straw and did not eat anything that could get caught in there, I was afraid of infection).
Now for the benefits - I LOVE SLEEPING THROUGH THE NIGHT!!! I did not know how much of an affect my breathing had on me. I always thought I had a small bladder and that the reason I peed several times a night was due to that - nope, I was wrong. I got up to go to the bathroom because I was already partially awake. I was not getting into a deep sleep and I was waking up with the apnea and not even realizing it. I sleep throught hte night now and feel amazing!! You son will be so happy with that!!
So, even though it was awful as an adult, I have spent the last 4 months fighting to get my DDs out. Hers are also huge and touch evenwithout infections. She has tremendous breathing problems in her sleep, but we a told by every specialist that she will "grow out of it". Forget that. I am going from specialist to specialist until someone takes her. They are coming out while she is a child so she does not have to go through the painful prcedure as an adult.
Good luck to your son, I promise, it was not be that bad and when it is over, it is done. He will have a whole new life once he is sleeping through the night!!
