Just Diagnosed with Small Fiber Neuropathy

Posted by boo55 @boo55, Feb 1, 2019

Hi . I am a bit scared here. Had positive skin biopsy for small fiber. What tests will the Neuro ask for to find causation? Was diagnosed prediabetic in Fall. My Dad had similar issues and eventually lost a toe. Always felt he was walking " on fire ". My feet have similar issues. This is just one big Ick. Boo

I had a normal EMG yesterday so I don’t have large fiber involvement. The Neurologist did the skin biopsy to see if it is small fiber which I think it might be. I hope to get results in a week or so. I had a normal EMG in 2005 when it first started however they didn’t have the skin biopsy then or it wasn’t offered. The pain actually lessened through the years but now it’s back with a vengeance. I also was diagnosed with Erythromelagia but it is relatively mild but the other nerve pain is vicious right now and am unable to do much. The Neurologist does not know what is causing the fasciculations in feet, toes, legs. I’m just wondering if it’s from nerve damage although the fasciculations usually occur in large fiber. It’s all so strange and difficult to figure out. Thank you for any insight you may have. -Laura

Hi, @lauraj155 - Just wanted to let you know I moved your discussion and combined it with an existing discussion in the Neuropathy group "Just Diagnosed with Small Fiber Neuropathy." This was to get you in discussion with some members who have small fiber neuropathy and see if others may have experienced fasciculations (twitching) with their disease and why this might be occurring with small fiber neuropathy. Hoping that @jakedduck1 @johnbishop @albiet @rwinney @pepperbeau might return to offer any insights on this.

Have you looked at getting another opinion about the cause of the fasciculations? Will you be undergoing treatment for these?

Hi @lauraj155 -- I'm not familiar with fasciculations but I can imagine that it's disconcerting if it's painful. I did find a little information that may be helpful but I'm not sure.

Another Perspective on Fasciculations: When is it not Caused by the Classic form of Amyotrophic Lateral Sclerosis or Progressive Spinal Atrophy?

Is it possible as @lisalucier mentioned to get a second opinion if your neurologist does not know what is causing it? Maybe they can provide a referral?

REPLY

@johnbishop, @lisalucier - Thank you for responding to my question. I have been extremely frustrated with the level of care that I have received from the Neurologist. I cannot find anything about fasciculations with small fiber neuropathy. I have it mainly in my left foot and big toe where most of the nerve pain is. I can barely walk due to the pain, however my EMG appears normal and still waiting on small fiber results. Yes, I will probably have to seek a Neurologist out of network for a second opinion. I appreciate your help. -Laura

I have sfn but I don't believe I have gluten sensitivity. My neurologist recommended I greatly reduce carbs and sugar. What a difference it has made! My feet and calves still burn but not near as intensely. On special occasions, I will have a wine, dessert or pizza and then notice an increase in burning by the next morning.

Hello and welcome. May I ask how and when will you be finding out your diagnosis? Before I jump in with two feet for you I would like to understand a bit more...if you are willing to share. You ask great questions and came to the right place for support, knowledge and encouragement.

I have had diagnosis of fibromyalgia since 2003.
Lots of other health diagnoses with chronic pain.
Last January both of my feet began to go numb with nerve pain after a nine day hospital stay with critical low sodium. Rheumatoid arthritis doctor sent me for punch biopsy of both feet. My lab
Pathology returned a diagnosis of small fiber
Polyneuropathy. My small nerves in both feet are dying as it also travels up both legs. In research I read it can affect the autonomic nervous system. I have all the symptoms heart arrhythmia’s, sluggish bowel,Retention post urine ect. Awaiting an appointment that I made 4 months ago to see
A neurologist that has a reputation for helping
With symptoms of problems that have not been
Researched or known a lot about. In my research
It saids the underlying problem is what causes
The symptoms. I am desperately trying to have
A doctor diagnosis my problem so maybe I can get pain relief and understand more. Does anyone else on site have these symptoms or have had a punch biopsy with this diagnosis?
How are you coping? I Am very interested in your
Case and opinion. Thanks for taking the time to read.

Hello @pieface1971. I moved your discussion and combined it with an existing discussion titled, "Just diagnosed with small fiber neuropathy." I did this so you could read through some of the members' previous experiences with receiving a diagnosis of SFN and so the members discussing it would see your post as well. If you are responding by email, you can click on VIEW & REPLY to be brought to the new discussion. As you work through some of your new symptoms and diagnosis, there is another active discussion on Connect about how to manage the pain with small fiber neuropathy.

I'd like to invite @boo55 @lauraj155 @lavieauxusa1972 @albiet @peggyn @lorirenee1 to share whether they can relate to any of the symptoms you mentioned you were having, @pieface1971:
- small nerves in both feet are dying as it also travels up both legs
- heart arrhythmias
- sluggish bowel
- retention post urine

They may also have some tips from their own experiences of how they have coped with their symptoms.

@reecey also mentioned being on the verge of being diagnosed with small fiber neuropathy. Do you now have a diagnosis, reecey?
