FWIW, I had my tonsils out when I was 41 years old. So you need a new doctor's opinion.
It was worse than you can imagine as far a rehabilitive pain. It was 19 days of horrrible pain (yes,I was counting) but once that was over it was a life changing surgery. I don't get sick as often, my colds last less than 5-6 days,I rarely get a sore throat and if I do it's maybe just a day. I sleep through the night, never waking up, no snoring. Just fall asleep and wake up rested. I had no idea people got restful sleep, I thought evryone just was tired becasue they tossed and turned all night.
I don't envy you, but it's well worth it after the recovery.
