--from my worst symptoms in those areas, one of the most confusing things about my acute-onset burning neuropathy (at least to neurologists) was the burning I had in my abdomen, shoulders, lower back--and there was no indication of spinal problems on MRI. I still get "flares" of these symptoms now and again.

Too many doctors, even neuros, don't realize that there is truncal neuropathy, especially when the small fibers are involved.
