It wouldn't surprise me if her doctors are honestly saying they don't know. 90% of med school is rote memorization and regurgitation of which peteol-based chemicals they call "medicine" to administer for a given symptom without learning much about the root causes of a given symptom.

I know hollistic healers who are vastly more educated about the human body, what the root causes of most illnesses are, and how to successfully treat, if not reverse than some of the"specialist" "doctors" I've interacted with.
