When I hit about 40, any and all scents started triggering migraines. They make the blood vessels in my temples contract. So, no scents of any kind. Dryer sheets seem to be the worst offenders! I had to forbid my son, who was grown and does his own laundry, from bringing a box of dryer sheets into the house. Or wearing his cologne in the house. Of course, he thought I was making it all up because I am an old hysterical woman...
It kills me to be around a woman who has doused herself in strong perfume. I just want to run.
