I’ve grown up a mouth breather and I snore quite badly now when I used to never snore growing up. I noticed at of the time I lay down that it becomes very difficult to breathe through my nose (it feels like the tissue is inflamed evenly on both sides),but when I was a teenager my pediatrician told me I did not have a deviated septum. Do you know what else might be causing this?

Yeah I’ve been thinking about it a lot lately. I don’t have any allergies that I know of. It seems to be some sort of pressure change when I lie down because if I’m having trouble breathing and I sit up my breathing usually becomes normal almost immediately or within a couple of minutes.
