Good Morning Alone!
When I have tests like Endoscopy and Cholonoscopy I can't have 'twight light' sleep because I keep waking up in major pain during the procedure....It's awful! Now I demand "Mac" anesthesia instead.....that's being put totally out.......NO MORE twight light sleep for me!

I had nerve conduction test......I think that's what you said you had......and it showed negative for PN also. I had to have the nerve/muscle biopsy before the dr. found the cause of my pain, Chronic Anxonal Neuropathy.
It sounds like you might have to just do all you can over there.......take your supplements and vitamins, change your diet and then come back here to get good (hopefully!) medical care. Good luck to you!!
