"The brain has great difficulty in pinpointing internal pain in the same way that it can external pain. In general it can only pinpoint pain in areas that we can touch. The brain identifies the location of internal pain in the best way it can. That is why the left arm aches when we have a heart attack. This is referred pain. Similarly, a problem with the shoulder muscles can make the wrist hurt."
Got it, thank you for that great explanation. After this latest liver flush, the *pain" shifted from the right shoulder to the canal between my left shoulder blade/spine, on up through my neck on that same side...do you know what this is indicative of?
