Thank you for all your answers. I really appreciate it. I don't think the grommet is blocked, not fully anyway. When I do the nose blowing thing air does come through it.
It was blocked but a bit of wax going back around early May. I was seeing ENT anyway and she said to use olive oil drops, as if she tried to take it out then it might pull the grommet out with it, so I did that. When my grommet was blocked then, no air would come through when I did the nose blowing thing.
That said, it has been sounding different from usual. A lot louder and weirder noises. I'm not sure if you can get the drops over the counter later, I'll check. Would these still be ok to use if the grommet isn't blocked?
I will get it checked jno. It's driving me mad, it's a bit disorientating and makes having conversations difficult.
