Is it common for symptoms to change sides?

My own PHP started on the left, then got better within a week or so, only to appear again on the opposite side, where it persisted.  This reminded me of numerous cases in the past where my clients complained of a similar pattern.  I came to expect it, for example, in cases of 'whiplash' injury to the neck.

I wonder, is this common phenomenon that no-one bothers to report on?  If so, it could be telling us something about the aetiology of the problem.  What is your experience?
