It's OK, I have been fielding these questions and concerns for 30+ years.
Of course people should always contact and consult a medical professional, but holistic methods and Kyusho methods still work from all those years of experience.
There is never just one way to do anything.
Why no upvotes though as I have answered your immediate concerns, maybe not the deep seated ones as only hands on experience can do that. By the way we do have medical backing for all we do, it is just mot accepted in EMT protocol... one day we will work toward that goal.
