Does stress cause vomiting?

  I'll be seeing the radiation oncologist in a week or so after the PET scan so I can mention it then.  I suppose it matters how much stress.  Like, when my mother passed that would probably be considered normal.  Some of this other stuff, I don't know.  Like getting into a pissing match with century link over their theft based billing practises may not be.  If I had to guess, I'd say it was the emotional aspect of what ever it is that induces it.  I've noticed I've gotten more sensitive to things that are morally wrong and it causes an amplified physical manifestation more so than it used to.  Another item to add to the never ending list of side affects.
