--may be due to cervical spine damage that might have well occurred in the fall. The distribution of symptoms seems to match up pretty well with cervical disc herniations or even frank cervical fracture pressing on the nerve roots and causing damage to axons into shoulder/arms/hands. What did the MRI show? Was the skin punch biopsy done only at the thigh and calf, or was an above elbow site included--in other words, according to what was the determination of small fiber neuropathy made? Do you have copies of your test results (you should) to share with us?

Since CRPS/RSD can also involve damage or destruction of axonal nerve fibers you might be"co-morbid" with damage stemming from multiple conditions. I am also interested in that you are indicating a first appointment with a neurologist now--it would seem with all this you should have been referred to one a long time ago . . .

In any case, I think your questions should involve how were your diagnoses arrived at, and is further testing indicated to try to find causes. Both impact upon possible treatment, whether that would be mostly symptomatic or aimed at a specific cause (again, you don't mention if you've had any treatment for any of this in the past).

In the meantime, do look through some of the material at the top of this board under the "Useful websites" area, which has a lot of links to databases that provide information about various neuropathy causes and presentations. Particularly, check out the Washington University neuromuscular database, written in doctor shorthand but very comprehensive:
