I have small fiber neuropathy and I am trying to decipher a gene report that associates voltage gated sodium channel blockers SCN9A, SCN10a and SCN11a with this disease. I have one homozygous mutation on SCN10a and several heterozygous mutations on SCN9a and SCN10a. Several of my SNPs on the report are either NG or NF. Basically, I’m not sure how to inpterpret all this.
How did the small fiber neuropathy start? Mine started after a viral infection. I’m seeing a specialist who is 99.5% sure I have mast cell activation disorder, but she’s also checking for autoimmune causes to nerve damage. I have POTS, blood pooling, fluctuating blood pressure, reduced vibration, discoloration and reduced temp feeling in my feet. I haven’t looked into the sodium channels. Maybe the sodium channel make you vulnerable if the immune system acts up or maybe it causes the immune system to act up? I’ll see what these extensive autoimmune blood tests show in a couple weeks.
My bloodwork showed I have mast activation syndrome and lupus. I had elevated double stranded DNA antibodies, low trypase (common in MCAS, but not Mastocytosis), very high prostaglandin D2, HLA B27 positive. I was also positive for Bartonella DNA in my urine, a chronic bacterial infection I must’ve got in 2014 when I got bit by fleas that were on a cat.
Mine started as a positive ANA and symptoms that seemed to indicate lupus. A year later I was diagnosed with Celiac and positive Lyme test. A couple years later I kept pushing for an answer as to why I had so much pain. It ended being diagnosed as SFN and a year later Dysautonomia causing POTS, stomach problems and now severe insomnia. Honestly I can’t keep up with what is happening. I believe I will ultimately be diagnosed with Parkinson’s or MS.
