I had full sinus surgery, was about 4 hours. My sinus were both 99% closed, I had chronic infections for years .
My recovery was brutal to be honest. I wasn't able to bend over at all for 8 weeks,could not blow my nose either. I had to do salt water flushes 4 times a day.

Had I known just how awful mine was going to be I would have never gone through with it.

Bit the end result ? I have not not had a single sinus infection in 6 years.

Felt so bizarre breathing through my nose lol

If you having endoscopic it should be so much easier.

End result is worth it
