As far as I know, the only kind of trauma that can cause an upper GI problem like reflux, would be one that was severe enough to damage your LES--a car accident, etc. It sounds as if you might have pulled a muscle in your effort to protect yourself from the falling dishes.
Hope you feel better soon!
