Are seasonal allergies an issue?
Even if mild, they could be a factor.
It would seem that seasonal allergies might be the issue.
Years ago my doctor recommended flonase as I had a post nasal drip in the winter. Probably caused by being shut in in enclosed spaces during the winter with heating systems going, less humidity, more dust in the air, etc. At that time he recommended it because a post nasal drip in the back of the throat could damage vocal cords over time. The reason for the raspy voices in some older people. I took it for awhile but stopped.
So, Flonase is over the counter now instead of prescription. I've been taking it for about a week and my AHI numbers have dropped from the 3.5-4.5 range down to the 1.0-2.0 range. It looks like I'll take it through the winter.
For those thinking they might have the same issues. Flonase is a mild steroid, different from the steroids we usually think of. It's not a nasal spray that's habit forming and doesn't seem to have any other physiological issues. Some people do report dry nostrils and a few report headaches though. But it doesn't have that list of warning often associated with some other medications.
Maybe someone will relate to this are seek relief.
