--have extreme sensitivity to chemical smells (and tastes); although admittedly I have had this all my life, well before the neuropathy.

But I've always wondered if having chemical sensitivity might make some of us more prone to certain conditions (including neuropathy).

There do seem to be considerable genetic differences in our ability to notice different odors/tastes, and in our senses of smell in general. I seem to remember the genetic ability to taste phenylalenine was located on the same allelle as the tendency towards extra-hairy ears (I certainly have those) and the ability to roll one's tongue into a tube (which I can do).

I find I have the ability to detect scents many other people cannot, and to find many scents (deodorants, perfumes, solvents) overpowering. At the same time, I find many odors pleasant that others find bothersome, such as spices like cumin or chili. I adore garlic and onions. (I am real interesting to sit next to after certain meals.)

This would be an interesting area to research--I know I haven't come across anything that connects chemical sensitivity/detection ability specifically to neuroapthy--although, of course, there are many toxic neuropathies resulting from exposure to chemicals that many are sensitive to.
