i had tonsilitis last week and was on penicillin for a week, finished taking my tablets yesterday and am having my op on tues. i rang and spoke to the nurse and she has no problem, neither does the surgeon. they said that as long as i felt ok and the infection had gone there wouldnt be any problem.
they dont want u taking aspirin as it thins the blood, but just take lots of paracetomol and ibuprofen and u should feel better soon, drink loads, and take vitimins. trust me u will feel better before u know it and will still be able to have the op!
i dont think they like operating when the infection is still there as it could complicate things, but i would defo speak to the nurse anyway.
hope that helps xx
