Smell or Eucalyptus Trigger Issues?

I've had four really good days.

Then, today I went to Sam's Club. Someone was sampling this smelly stuff for joint pain, like an Icy Hot wannabe. She squirted some on my hand and I rubbed it on my neck and almost instantly my guts started cramping.

I haven't been doing real good anyway, so it may have nothing to do with it.

Has anyone else ever had something like this happen? From either that eucalyptusy tingle or because it smelled to high heaven?

One time I found a bottle of peppermint oil in my cabinet. I took a whiff. Nice! Got diarrhea. Well, okay weird. Was it the oil? Sniff. Diarrhea. So yes, but no problems with Icy Hot. That oil wasn't diluted or anything.
