bleeding is not a definite.
i had my tonsils out in 2009 at age 22.
i didn't bleed at all.
the pain isn't usually that bad during the first day or two but its important to take the pain meds anyways so they are in your system.
day 3-4 the pain gets worse.
day 5-8 the pain is pretty unbearable especially due to the "referred pain" which means your throat tells your brain they can't take any more pain so your brain is like ok, no worries, i'll just spread the rest of the pain to your head and ears.
what is causing the pain is the scabs forming.
once the scabs come off around day 8-9 the pain decreases dramatically.
day 10-11 the pain is pretty much gone.
the scabs are disgusting. they cause the worst smell/taste you've ever had.
when they want to come off you start to feel like you need to cough and the feeling just does not go away until you cough them off.
you're supposed to avoid dairy as it produces mucus and that can make you congested and feel like you need to cough which can make the scabs come off before they should.
for the first 3 days you are supposed to have liquids avoiding red ones. liquids are things like water, juice, popsicles (don't suck on them though mush them up in a bowl), jello, and broth.
after that you can start eating very soft foods like apple sauce, scrambled eggs, mac n cheese, mashed potatoes, baked beans, peas....
generally you stay on that diet until you go for your 10 day post op appointment and your dr gives the ok to eat more normal foods.
you are supposed to avoid eating rough foods like potato chips and pretzels for 3 weeks.
you are also supposed to avoid using a straw for 3 weeks.
and you are not to use ibuprofen (advil/motrin) for 3 weeks prior to and 3 weeks after as they can thin your blood.
one other thing is you are supposed to stay "close to home" for 4-6 weeks.
i also had sinus and septum surgery a couple years after that and even though there were much fewer restrictions i'd much rather go through a tonsillectomy again than that surgery.
