I am very well aware of the nasal cycle personally. If I'm in a dusty environment for too long, I get an itchy, achy swelling high up in one side of the nasal cavities, and only on that side, until it changes after a few hours. The first few times it happened was at 40 y/o, and at work in an office building. I mistook it for migraine, and was flummoxed when my migraine pills did not work. When I understood that the irritant was in the office air, I tried to take it up with people higher up but to no avail, so I had no choice but to quit that job. Luckily, Aspirin (-type drugs: "NSAID") work against symptoms, but is not a long-term solution.
