Update: I just learned about something called "inferior turbinate hypertrophy". I also learned that a deviated septum can aggravate nose-based apneas.
Based on the description of turbinates (bony protrusions in the nose), I now believe that the flaps I originally felt were in fact turbinates and not nasal polyps. While turbinates are a natural and healthy aspect of the nose, they can sometimes cause problems when enlarged. It seems that I will need to see an ENT doctor to confirm.
Nasal sprays and washes have been effective, but I continue to experience a post-nasal drip in the back of my throat, which continues to interfere with my breathing during sleep. Antihistamines appear to be of little help. HEPA air filtration seems to improve symptoms but does not eliminate them. Flonase and antihistamines occasionally causd nosebleeds, resulting in dried blood accumulating in my throat and causing apneas. Mouth breathing made matters worse by causing dried mucus to cake up inside my throat.
If CPAP doesn't seem to be working for you, I highly encourage you to see an ENT doctor and maybe even an allergist. That's my two cents.
Particularly on causes of CSA?
They are probably nasal polyps. Nasal polyps are known to cause sleep apnea particularly in young, fit people such as myself. Sleep apnea associated with nasal polyps, or "CRSwNP" as it's known to ENTs, tends to be harder to diagnose by means of standard tests.
I have stopped cpap and commenced a disciplined regime of saline nasal irrigation via neti pot combined with twice daily flonase spray. My previous use of flonase was sporadic. I believe my sinuses may have been irritated from long-term exposure to bleach in my apartment.
If necessary, I will go on antihistamines. Regarding my sleep study results, I am still awaiting.
Hi! I've been dealing with sleep apnea for 8 months now. Had trouble getting an official diagnosis. Doctors dragging their feet on me, possibly bc covid or bc medicaid. Gave up a few days ago and bought cpap on craigslist. Resmed aircurve vauto with phillips nasal cushion mask. Trying to figure this thing out myself.
I thought i had finally gotten the settings (pressure in/out, timing, humidity) and mask fit figured out, but it seems that every time i use the machine it gets harder and harder to breathe (with or without the machine), especially through my nose. Feeling around in there (please excuse me), i can feel there are these flap-like things sticking out about half an inch in on either nostril blocking much of the airflow. Not sure if they're nasal fluids or loose skin or what, but whatever they are, they dont want to come loose and i aint gonna force them to. Flonase nasal spray not helping and maybe even making it worse. Will be buying a full face mask craigslist so i can breathe thru mouth but it wont arrive for a week. I also lowered pressure (was at 8 before, 4 for exhaling) for tonight in case that causes the problem. Report shows 12 events per hour, reality is actually worse than that because its gotten progressively worse and because i know there have been a lot of subclinical apneas of 20 or 30 seconds apiece.
