Could be. I've met people with chem sensitivities (in groups of patients sitting through day-long sublingual testing), and they report an amazing variety of symptoms. Some coughed, sneezed, had itchy eyes or sore throats. Some had extensive rashes. Some became hyper, or had mood swings, or fell asleep. Some become unable to sleep, or develop central apnea. Some had headaches, body aches, muscle spasms. Some became dizzy or nauseated. One fainted.
Many had multiple systems affected. Lucky me, I'm in that group.
Symptoms can also come or go over time. By very carefully limiting my exposures, I have gotten "better" enough over the past 25 years that I can now risk going out in public once in awhile, but I can still get major whaps on occasion. Last time I was cornered in conversation with a friend of my daughter's who was wearing toxic levels of perfume, I ended up with a migraine so bad I vomited on my way home, 24-hour "flu" symptoms, and no sleep for 2 nights. This is serious trouble for those of us who have it.
Good for you for giving up some of those incredibly nasty products. The natural stuff really works about as well, and sometimes better, for much less $. Be aware that cosmetics can also give off traces of chemicals, especially hair products, that can affect other people. I've had to leave several times when a woman who uses hair spray comes to my church.
I suggest you keep a notebook of possible connections, as this can become hard to sort out otherwise. I actually made a chart with all potential problem chemicals down one side, and reactions across the top. Kept adding to both lists over a couple of years. Put an X each time symptoms occurred following any exposures. Patterns emerged over time.
Wishing you success in your search.
