My sense of smell doesn't get dull but I will smell cigarette smoke or some other smoke like scent, and my son and I don't smoke and noone comes to my apt. That does either. It's very weird.

I wondered about that. That is the first time I've heard of an olfactory migraine, I'll have to Google it! Have a good day.

I smell smoke sometimes before a migraine. I was told it is an aura. Olfactory Aura. My sense of smell is much stronger that before I had migraines.

Yes- Only mine normally goes the opposite direction and gets more sensitive to everything.

Yes mine has been goin on for 7 days i cant get it to subside ive been in the dark i eat thinking maybe that help i sleep nothin is working. Could it be stress? Blood pressure maybe high i need some relief😩
