Thank you all for sharing, it's nice to know I'm not crazy. Some days I feel like it's all in my head. That's probably weird

Yes I have exactly the same thing. I also have all year round allergies. It's a sensitivity to chemicals. I went to an allergy specialist as I became allergic to perfumes, air freshners, cleaning products etc and it was very severe. Pain behind the eyes, headaches,feeling hot and itchy etc. That's actually what lead them to diagnose me with fibro in that consultation. Stay away from strong chemicals, if you can't avoid them take some antihistamines as it is caused by an irritation in your nose. I also use a balm you get for allergies that you run inside the nose when I have to travel on public transport. Or a steroid nasal spray. I have no strong chemicals in my house and I haven't had an issue in months.

I was looking at an answer above & so true on perfumes. Remember when they started putting pear in everything? That gagged me, made me ill & headaches galore. I use a lot of Hermés products & never have a problem anymore. Even bought some for my sig ot.

I can't stand to walk down the pet food isle at the store,

Yeah I do with different smells, I suffer from chronic migraines. I have to watch what I use and so does my partner. My worst smell is bleach, honestly think that I am going to die when I smell it. It can send me into a migraine for at least 3 days plus x
