WORKED TEMPORARILY
Wow! What a rush! I woke up with sinus pain today, and came looking for remedies. After reading all the reviews on snorting cayenne pepper, I tentatively decided to give it a try. I sprinkled a pinch in my palm and used my pinky finger to scoop a TINY amount under my fingernail, and I inhaled it with my slightly clearer nostril. The burning got pretty intense within a few seconds, but within 30 seconds something shifted and I felt the pressure drop away. After a couple of minutes, I used it in the completely blocked nostril and it cleared almost immediately! Yes, the burning was INTENSE, but it was never unbearable. Honestly, it was a relief to feel something other than my sinus pressure and pain. I've heard of pharmaceutical companies using the chemical in pepper to find new ways to block pain- my experience shows that, at least temporarily, IT WORKS!
Unfortunately, the pressure is already coming back. So, it works in the short term, but no lasting relief. I will try reapplying. If I find different results, I'll post them.
