Irritation from certain smells and environmental allergens, bright lights, and loud noises are all sensitivities that Fibromyalgia brings.

I've had it my whole adult life and had no idea I had fibro until 2 years ago

So it's not on the list for fibromyalgia symptoms. But could be a symptom
I have had issues since I was 27. ,in 42 now and it's so bad.

I have post nasal drip, which when around strong smells the nasal drip gets bad and causes me to asthma attack.
I love perfumes and scented candles, but hate what it leads to.

I've always been extremely, nauseatingly sensitive to smells. Basically, a bloodhound detective. The scarf trick is useful. I once ended a date before it began bc of the obnoxious overuse of cologne, I was not going to be trapped in a car with THAT!!!
10 years ago I developed all kinds of allergies and now I perpetually have a runny, stuffy, bloody, raw nose.
The sensitivity is also somewhat responsible for constant headaches. I also would reccommend keeping a small vial of peppermint essential oil on hand. Or something you like to smell. A small whiff or dab can overcome potent smells and help
