Haven't read other replies so sorry in advance if i repeat anyting already said.
My dd had her adenoids out 4 weeks ago,she only went in for grommets but they looked had her adenoids at the same time,said they were enlarged and whipped them out.
There were 5 kids in total having the same op,apart from a boy of 2 having tonsillectomy aswell,they were all kept in overnight and discharged the next morning-all except my daughter that is!
d.d was complaining of sore throat and was generally unwell in herself so they kept her in another night.
On our way home the next day her nose srated to bleed terribly,we couldn't stop the bleeding so we took her straight back to hospital,they checked her bloods and said she had caught an infection so she had to to go on an I.V drip.
It took a good 2 weeks to get her back to normal,eating again and back to school but now she is absolutely fine.
I kept in touch with 3 out of the 4 other kids and only my dd has had problems so it must be rare.
looking at the advice/discharge sheet they generally reccomend-
3 days indoors,away from other children if poss
a further 7 days off school(won't apply to you)
any bleeding from nose of throat MUST be checked out
