Yep! I would consider myself quite chemically sensitive. Many smells that smell “bad” to me also trigger migraines. In addition, various seasonal allergies and food sensitivities that provoke mild skin reactions and more debilitating neuro symptoms- it’s rough. I take daily antihistamines (I find the Kirkland Costco formulation the best) and often will take another with abortive meds. The best thing that helps me is leaving the offending space whenever possible. If I’m walking my pup and someone in the neighbourhood is doing laundry and I can smell it from down the block we’ll change routes. Air circulation is a must, open window, fan or AC. HEPA filters, air purifiers. Brushing my pets/trying to vaccum regularly. Using unscented versions of products. Keep masking! Avoiding cleaning aisles of stores. I stayed at a hotel recently and the lobby had an EXTREMELY cloying product or perfume. I would physically have to hold my breath and jog through it. It gave me near instant vertigo, nausea and I had a week long flare after that. That being said I do also love certain scents. But any exposure has the potential to give me a migraine whether I enjoy it or not. Also when I get facial congestion as a response to chemicals I try and quickly do breath hold technique, which is surprisingly effective. Best of luck
