that is quite a distinction you have observed. i wonder if it has to do more with the external part or with the placement. seems to me that there are chakras along that midline of the body. and there is the accupunture/pressure points. i wonder what this corresponds to?
my wife has an extremely tender spot on her left foot and the chart shows it corresponding to the solar plexus. interestingly, she has had a gastro bypass. it has been over decade, though. the surgery, that is. the tender spot is a palpable mass.
