I read your post with some interest, as I am looking for a thread that discusses CIRS (Chronic Inflammatory Response Syndrome). I have been looking for answers to my idiopathic PN diagnosis for a few years. While researching a health problem for another family member, I stumbled across mold illness and the go-to website called ************* and Dr. Shoemaker. The biotoxins in mold found in water damaged buildings will cause an array of inflammatory processes including peripheral neuropathy, but only in about 20% of the general population who are genetically identified. The symptom page of the ************* site lists the many inflammatory responses identified. It turns out I had a few other symptoms that I was just living with, like leaky gut and MARCoNS.
