well im 29, had my tonsillectomy on Wednesday at 11am. its now saturday and up until now it hasnt been too bad, they say to eat rough food, it hurts but push through it as it clears the gunk off the area. fluids are a must , as much as u can.
As i said , it hurts like crazy to eat and drink but you have to push through.
I havent been to bad until today (think its day 3 post op), now my throat is so swollen swallowing my own saliva hurts, keep your pain meds up, its easier to keep the pain away than it is to get rid of it when it sets hold!.
Im sure you will be fine though, just think ahead of not as many batches of tonsillitus!
