Nasal Cycle

Sometimes I even hear a squeeky sound as the tissue inside the nose contracts.
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.
