Many of us have a multitude of symptoms similar to Chiari, without actually having the blatant medical ‘signs’, of what would be recognised in the medical world, as Chiari 1 Malformation. You see it’s not as ‘clean-cut’ as the medical fraternity think it is, it’s all dependent upon:-
changes in intercranial pressure,
subtle (or sometimes blatant) instability at the craniocervical junction,
restrictions at the craniocervical junction – caused by
herniated hind brain,
or malpositioned C1 vertebrae,
or anything else that can cause ‘crowding’ and hinderance to the flow of cerebro-spinal fluid, in that area.
