--even though you've listed a number of test results, I doubt you've had a number of the tests that should be performed for those with neural symptoms.

It's good that you've had heavy metals checked, but beyond the blood sugars, have they done any other metabolic (i.e., thyroid) tests or extensive autoimmune tests that are not anti-nuclear-antibody (ANA) related? (Too many doctors seem to stop if ANA is negative--even rheumatologists.)

There is a wonderful spreadsheet at www.lizajane.org that lists tests for neural symptoms in a spreadsheet format (for tracking results over time, among other things); you may want to look at this and see what you've had to this point. (A number of us worked on this with the originator, who also posts here.)

There's also this list of initial serum tests from Quest diagnostics:

And, yes, reflex sympathetic dystrophy/complex regional pain syndrome should be considred:
