They can test your B12 level.
Sometimes B12 is not absorbed in the stomach and must be given by a shot once per month.
My experience with PN (as an RN and Clinical Exercise Specialist) is you can't always find a reason for what ails you and some of it is just the condition.
Some of it can be managed, some can't. I have a whopping case of sensory and autonomic neuropathy, and to be honest, pain is a pain (and life altering-It brings me to my knees if I can stand up that day), but the autonomic system going bad is life threatening....I gotta just live with that. It is like a time bomb....I can live to 100 or keel over today.
Despite struggling to live a full life, I am not planning on jumping out of any perfectly good airplanes for kicks, but I do a lot of stuff that a healthy 20 year old male would not consider doing (my finger was nicely reattached after I cut off the tip off kite-skiing---Ok, so I gave THAT up--thankfully due to PN, I didn't feel much---it was the finger or a dunk in a frozen 200 foot deep lake with a big hole in it I didn't see until too late, at my rate of speed...I must say the EMTs were impressed with my incredibly low pulse and blood pressure........I am so sick I come across like a trained athlete, LOL)
I am a 54 year old female with a more than a few hard knocks from life. I can be utterly immobile for weeks at a time, or flying past very fast. Either way, people don't see me.
EMGs don't diagnose small fiber neuropathy as well as skin biopsy...epidermal biopsies they are called. These biopsies confirm if you have small fiber neuropathy. I can't imagine putting you thru a lot of EMGs for no good reason. My EMGs are normal.
I read you walk, keep walking....you too Susie (saw this in some other post)...I am one of those crazy trail riding cyclists (on a good day

)....I usually just say 'On your left'....we see people, don't worry. I am probably more dangerous in a car....most of us are. I walk on a bike trail too, and no cyclist has run me over yet, the fast ones are far less dangerous than the putzers.
The ones that fly by, can usually handle going off the trail to avoid a crash with a person.....they kinda like that stuff.

If they crash, you get a good laugh....if they get to close to you, yell at them that, them your son in law is a lawyer....

You pay for the trail too!
