One of my triggers is very common among migraineurs: hypersensitivity to scents. I have all the other common triggers as well.
Obviously, I avoid scents as much as humanly possible. I also politely request all visitors not to wear scents and use all scent-free products.
We had a scent in our home recently that took days to air out, despite all professional recommended measures. Our weather was ideal and all windows and doors were open. I had one of my worst migraines during that time, as I couldn't leave the home for that length of time. I will say a lingering scent is very rare, however.
Also, many times even brief exposure to scents triggers a migraine. My husband and children cooperate, understand and are completely on board. (I feel so guilty because of my extreme sensitivity.)
Once you're exposed to a triggering scent, do you do anything? I've tried initial avoidance as well as saline nasal sprays and smelling lavender, peppermint oils. Any other ideas?
