I started get PND six years ago. It was really bad at various times and would keep me awake at night as I just couldn’t clear my throat.
I was referred to an ENT specialist a couple of years in and they looked for polyps but couldn’t see any issues (he put a camera up my nose/down my throat) and he suggested it might be allergies. I took anti histamines for months but they made no difference. I had been using otrivine regularly after getting hooked on it after a cold, and I did wonder if that had buggered up my “drainage system” but I came off it and haven’t used it for couple of years now.
After reading about silent reflux being a possible cause I started on omeprazole, but I’ve been taking that for a couple of weeks and it’s made no difference.
Is there anything else it could be?
