It's now going on 3 months that I've been having nasal/sinus congestion. It started in the midst of a Candida cleanse. Initially I searched for help for nasal congestion, since there is no apparent sinus infection. But as I've continued looking for answers, I find that anything that's been going on as long as this is considered chronic sinusitis. I've had bouts of sinusitis in my past. But there is no sign of infection here. The congestion is dry, no discharge, not even much clear discharge. I learned from my GP that my nostrils were too dry, and began using grease, instead of the saline spray I'd tried. I've now had 4 acupuncture sessions, but nothing is halting this process. My impression is that it's a mast cell issue. Antihistamines haven't been much help. I'm using several things as mast cell stabilizers, but the congestion continues. Since yesterday, I've added some Butyko breathing, trying to reset what has now become very unbalanced breathing patterns, as I try too hard to pull air in. I've used an OTC decongestant spray 3 times during this period. It's worked brilliantly, 2 sprays each nostril. But, it's anti-cholinergic, and the rebound was obvious over the next 2 days. I won't be using this again, no matter how difficult sleeping is. Everything I've tried seems to help a bit. But, on the other hand, I could equally say, nothing works. Royal jelly and mangosteen for mast cells, anti-inflammatory, anti-histamine, Neuroprotek for brain mast cell activity, breathing: each seems to work, sort of. But not for long. Saline rinse does nothing.The congestion seems to have it's own dynamic, which increases my suspicion that it's a mast cell problem. Suddenly there will be no problem at all, minutes later breathing's impossible. My limited understanding is that polyps can develop from sinusitis, but I don't think there's anything to suggest that here. Up until the last few days, it reliably began at 8PM. The last few days, I've not been without congestion, possibly stirred up by the acupuncture appointment. I've been sleeping sitting straight upright for the past 3 nights. I'm in agony!!! Any ideas of a direction to pursue?
