Have you heard of synaesthesia? Basically, in a nutshell, it's the crosswiring of senses.

I'm not an expert or anything like that, but smells=bodily feelings sounds like it to me. :)

If you'd like, there's a community here, synaesthesis, that is devoted strictly to synaesthesia. There's also a community, sensedefence, that deals with overly sensitive individuals, which sounds like it would apply to you, at least during your period!

Anyway, just a thought.
