@zaa I think the one thing that ties a lot of the effects of nasal passage blocked for me is poor quality of sleep which the body needs to stay healthy. I also have obstructive sleep apnea which was diagnosed a few years ago and I now use a CPAP which helps. I'm hoping my latest ENT appointment and treatment plan of the twice a day nasal rinse and the Mayo Clinic nasal spray will improve my sleep and over all quality of life with better breathing. Sleep is a key for many different conditions.
Seems like nasal rinses have been good for me but are you finding your nose to be very dry afterwards? Is there any issues with rinsing twice a day forever? I use a saline spray which helps moisturize afterwards but I’m going to try and get the Mayo spray you mention if I can get my ent to help out.
