Toxicity and Chiari

I know that I have read some posts along the way discussing Chiari and toxicity. I suspect this illness is far more complicated and intertwined than at least my doctors imagine. I'd love to hear people's opinions on how build up of toxins in our environment, or from anesthesia and other medical treatments, are possibly contributing.

Since I was a small child, I have had very extreme reactions to things like perfumes and detergents. Just wondering whether this might be a piece of my puzzle.

Thanks all!
