Dahlek,
If you could define your need for understanding clearly and in detail, that would certainly be worth its own thread. My understanding is that you want to know how to deal powerfully and effectively with health issues that cause falling, fractures, and intractable pain. Is that right? Another way to put its, is what you're asking how to live a life worth living with PN, fibromyalgia, chronic fatigue syndrome, general autoimmune disorder, rheumatoid arthritis, and other debilitating, extremely painful chronic diseases with no cure and few effective treatments?
What you bring up is exactly the type of issue that caused an explosive increase in knowledge about PN and techniques to cope with PN in the previous Braintalk forum.
Physicians and neurologists lurked and were active in the old Braintalk forum and and are in this forum. For obvious legal and social reasons, they participate as peers rather than as physicians, but I'm sure that we've helped move the knowledge and practice of medicine forward in regard to PN and associated issues through our professional participants. .
This isn't a complete answer to what you're asking, but I found the book "
Sick and Tired of Feeling Sick and Tired: Living with Invisible Chronic Illness" to be full of helpful insights and advise.
