A couple of weeks ago I found a comment on another forum that suggested that congestion of nose and ear seemed to be linked to excessive serotonin. Looking into it I found the following:
"Conclusion Serotonin receptors are highly expressed in patients with chronic rhinosinusitis with nasal polyposis in both turbinate and polypoidal tissues which proves that serotonin has a strong role in the formation and growth of nasal polypi and allergic reactions."

Then I came across a post on another site where someone said he'd been pretty much free of congestion for the past 9 months, while drinking lots of coffee, and taking aspirin. Now, I've read that about 30% of, sufferers have aspirin intolerance, also known as AERD, or Samter's Triad. Often they need to avoid high salicylate foods also. They often have asthma too. If this is you DON'T take aspirin, please! For me, aspirin has always tended to shrink the polyps slightly.
So I searched for factors that raise, and factors that lower serotonin. I'd been doing lots of melatonin, which raises serotonin, so I dropped that, and raised my coffee (which lowers serotonin) intake from my usual 3 cups a day to 5 cups a day. I took 1 aspirin after each meal. I took 1 Pepcid (famotidine, which lowers serotonin) a day.
Within a week my nose was almost entirely clear, visible swelling gone, sense of smell back, barely using any tissues. Within 2 weeks nose in great shape, breathing easily and fully, no more runny nose, acute sense of small. Not bothering with the aspirin or famotidine any more, enjoying 4 or 5 cups of strong black coffee daily, 2 first thing in the morning, none too near bedtime, sleeping about as well as when I was taking melatonin.
