Sjogrens Syndrome and sinus drainage

I’ve had Sjögren’s for years. Dry eyes, nose, mouth! I’m trying to find out if anyone else has had issues with non stop drainage in the throat. I have bulging neck disc as well. I can’t wear a cpap which I need badly. I sleep in a recliner thanks to a failed lumbar fusion April 2023 . Setting up I still choke on the drainage they say it’s not the deviated septum , I’m starting allergy shots next week but taking sinus meds doesn’t help it. Now I can be walking and look down and it’s like a bucket dumped in my throat and I start choking. I also have an Arachnoid cyst on my brain but I was told it has no effect on it causing this.
