You made mention from about 3.40 that that condition of arthritis development inside the socet/ shoulder joint itself fall outside of your field and that that is usually treated surgically. 

I've had first hand experience of that kind of problem which, I'm sad to say , that medical field is perhaps incapable of properly assess the problem and connecting the dots how to solve it when it was so very easy for me eventually. I told the GP as well as the Orthopaedic Surgeon specifically that when I rotated the shoulder it felt to me as if there was sand grinding inside that joint. Secondly my problem first only affected on shoulder and only two week later , the second shoulder in much the same way .

Then I suffer cardiac arrest and had to undergo bypass surgery and neither my GP nor Specialist could or would say anything . How could they not have connected the dots unless they never care or they are just over rated and not up to the task of solving sometimes very simple medical problems daily traumatizing millions of patients. My sudden cardiac arrest and the prior progression of that condition from the one to both shoulders indicated to me that there definitely was a definite causal connection between the arthritis that developed in both shoulders and the cardiac arrest.

When I recovered after surgery I searched and found the answer. In the months before I developed the arthritis symptoms I bought and consumed Calmag I bought from Dischem Pharmacy in the hope ( like many do ) that it will supplement my bodies' need for Calsium and Magnesium. Since I have previously learnt how to mix my own calmag formula in order to get both elements in a foodstate ( many years before) I instantly predicted that I would find a disclaimer on the product and indeed it was there in fine print on closer inspection. That it was not guerenteed to be in a food state. Why I asked myself and I answered that question myself. Because it needs an acid and usually ACV ( all in a particular ratio ) to put it in a food state. Otherwise that stone ( which is calsium) will not enter the bone as it's intended destination. No absorption was likely to take place.

And so at the Chemical level I decided to experiment and predict that if I consume 2 tsp of ACV in lukewarm water then there was a chance that my arthritis in my shoulders could become history. And wallah.... only two days and I suddenly reversed all the problems I had at root level. I was in days able to wash my own back again ; a feat that was completely impossible despite about 10 days in physiotherapy.

Moral of the story is that people's attention is so much focused by Big Pharma and Medicine on cholesterol as the biggest culprit in heart problems when blood flow problems are artificially created by calcium intake that's not in a food state. They cause calcification and hardening of arteries that narrows down to limit and even stop blood flow leading to heart attacks more than I believe cholesterol is responsible for. Point I wanted to make about treating that specific arthritis condition surgically is a huge mistake. Classically, it will not solve the problem as always. A simple chemical intervention of ACV in the gamechanger.
