So very sorry to hear of your son's accident.  Can you check out the
www.emofree.com site for the tapping points and words to use?  This stuff is
marvelous and almost frightening in its efficacy.  You can tap on points
other than those on the head.  No kidding--it is almost miraculous, but is
really just accupressure.  I truly hope your son does well.  best wishes,
pj
