Septoplasty and turbinate reduction surgery: Decongestant

Hi Guys,

Am new here. Anyways, I am having surgery on the 16 January by the method of FESS. I would like to ask whether anyone that has undergone the surgery knows if you can a decongestant weeks before the surgery and even possibly the day/night before the surgery? As some would know, long term decongestant use (3 days +) usually involves a complication of rebound congestion where you nose is actually more blocked after it wears off. It is a terrible feeling to have and I have it right now.

PRetty much would like some insight, information, feedback on whether I should be able to use a decongestant for the remaining 2 weeks until my surgery (can't wait!). I won't be able to see/ask my surgeon since he is on holidays until the 9 of January :(

any help would be greatly appreciated!
Cheers.
