All I could tell you is what I saw with my own two eyes. My wife was dying from her disease, but she had to work the system to get what she needed to help her live a somewhat normal life while she could.
YOu can call it BS all you want. That doesn't change the facts.
Your post #10 is what is replied to. Yes MD’s can damn well tell if a person has nerve problems in their spine or PN in their legs. Anyone with cancer who goes to a cancer clinic can get pain meds. My wife has had cancer twice, PN, add charcot foot plus her life has been saved 9 times.
