Nasal endoscopy

I had one last year (if that is where they thread a tube (with a camera attached) through your nose and down your throat?). They freeze your throat first, then pass the tube through your nose and then ask you to swallow, I was aware of a slight feeling that something was at the back of my throat, but it wasn't a big deal; I never felt the tube going up my nose or down my throat, so don't worry, it really wasn't unpleasant at all.

I had one a couple of months ago and will be having another very soon.It wasn’t painful and at the point I thought this is getting uncomfortable it was over,

I didn’t like mine as they struggled to get it up through the top of my nose. Mine was to check the vocal cords & then into my lung. They did give me something but took ages to kick in.
If it’s just the nose, it shouldn’t be too bad.

I had one about nine years ago for a swelling that kept coming and going in my neck, it was a pretty quick procedure, I don’t recall it being painful, just odd.

Yes, I had a nasal endoscopy last year as I've had a lot of sinus problems.

Mine wasn't a complete success as it was found I've got a deviated septum which meant the probe couldn't get entirely through my nasal passage.

Laying out flat I found the procedure a bit uncomfortable, with a certain amount of stinging, but all bearable.
