Well it’s hard to say. It does sound like something to do with your work.
As for keeping the allergen out of your home, you may need to undress in the laundry room and put your clothes directly into the washing machine. Also take a shower and wash your hair. This is just a guess try and see if it works. Good luck.

Overall he is in excellent health for his age (63). We started eating “Paleo about 4 months ago and this started soon after. We thought it was gluten sensitivity but ruled that out when he had no problem with baked goods. He can drink most bottled beer and other alcohol including wine. Just today he is having trouble in our home and car with the allergen. Apparently I am coming home with it. Any suggestions for cleaning it from my home would also be appreciated.

What happens when he drinks beer at home (or anywhere else)? What about other alcohol?
How does he feel generally? Ask him to think about how he felt five years ago, any difference?

The same thing happened to me. I loved vinegar but around my 40th birthday it started making me flush and the roof of my mouth to swell. I ate it only occasionally after that. Then once I drank some and about an hour later was in agony with severe cramps, chest pain, vomitting , shakiness and I could hardly breathe. I called 911 who didnt believe I was having a vingar allergy. After a few hours at the hospital and lots of water my reaction calmed down and I was fine. I haven’t eaten any since.

Some parents notice that there does seem to be a link between what their autistic children eat and their behavior. This is not necessarily an allergy, however it is an indication.

Nobody knows what causes Autism. What is the source of this BS.

I have not tried that. I will talk it over with my doctor. She seems to think that I need to see a nuerologist, again. But I am up to my eyes in bills for all these expensive tests, and only one has shown anything, but not enough for them to tell me what is wrong. I’ll talk to her about TMJD/TMD. Thank you for all of your advice!!
