Unknown Cause or Idiopathic SFN

Posted by katec @katec, Nov 5, 2019

Hello. I was wondering if there were any folks out there who were at one point labeled “idiopathic” or “unknown cause” SFN, BUT later found the cause?

I’m asking because my son (15 years old) has a positive biopsy for SFN. We have done every blood test imaginable and thorough genetic testing to try and pinpoint what is causing his SFN so we can guide treatment. So far, nothing shows up out of the ordinary on any test. His B12 is high, which is weird since he is homozygous for MTHFR, but other than that everything comes back normal on blood tests and his genetic testing shows no known mutations.

His doctors have tried many medications and he doesn’t respond to those in either a negative or positive way. The doctors are pretty stumped, so I was wondering if anyone else has had a similar situation and finally did find something (maybe outside the box of normal testing) that they think is causing the SFN and were better able to treat it? Ideally we’d like it to be autoimmune, so we could start IVIG or another type of immunotherapy (even though he didn’t respond to a 30 day high dose of prednisone) but nothing in his bloodwork is pointing in that direction.

Thanks so much!

Hello @jennyw, welcome to Mayo Clinic Connect. Thank you for sharing this information about the connection between gluten sensitivity and neuropathy. I knew sugar and diabetes are players that can induce neuropathy but wasn't aware of the gluten connection. Here's some more information for others who may be curious.

Did changing your diet help with your neuropathy symptoms?

Hi John, I started another discussion which details my experience. I can't work out how to connect that discussion but it was titled 'Gluten intolerance and peripheral neuropathy'.

@johnbishop John and and anyone that can comment, I’ve been feeling terrible lately and wondering if anyone would attribute these to SFN – tinnitus, exhaustion , chattering teeth, tingling buzzing in extremities. I’m at my wits end.

@albeit I'm sorry to hear you are feeling terrible and are at your wits end. I know it can be difficult dealing with neuropathy. My only symptom from my small fiber PN is numbness so I don't need the pain meds. I take supplements which have helped get rid of pain symptoms for others taking the same supplements. I shared my story in an earlier post along with the links to where I found the supplements in a closed Facebook group.

Is there anyone else doing The Protocol or have tried it?

I’ve been on it since Sept 2016 but I only have numbness. I feel it has stopped the progression of PN in my legs. After 2 months of taking it, the numbness was reversed some but no progress since but it hasn’t gotten any worse either. The Facebook group has over 9000 members, a lot who have pain and other symptoms which have been relieved without having to take any drugs. You can find all of the success stories by searching the group using #theprotocolworks.

Here’s the link to the group which you need to join and will have a lot of reading to do.

Hi Kate
I've been taking this protocol for 4 months with slight alterations. My neurologist recommended Acetyl L Carnatine and Alpha Lipoic Acid but, only when I asked him. Never offered it up as a suggestion prior. I think its worked well overall. It's no game changer for me pain wise but always hoping it's having a positive effect. Another good possibility to add may be Turmeric. Good luck if you decide to try it for your son and might want to run it by his Dr. first. Take care.

Be careful with Turmeric. I was happily taking it until my neurologist told me it could make my SPN worse because it elevated vitamin B 6. He tested my B6 levels and it was quite high so he strongly advised me to stop taking it. I take Alph Lipoic Acid, but have not noticed any change. Not sure what L Carnatine is, but will check it out

I meant SFN not SPN
