Not to be a know-it-all, he said after googling, but most people have allergies to male cottonwood pollen, which is pretty much gone by the time the seeds are being released by the female trees. I ain't a doctor, but I suspect the culprit is something pollinating after the cottonwood have their sex. Good luck
