I believe autonomic nerve damage impacts body temperature regulation. I have idiopathic small fiber neuropathy confirmed with punch biopsy in 2017. In addition to spinal stenosis and cervical myelopathy (had ACDF surgery), I have started to notice significant CNS/PNS decline. It is like my brain and body are not communicating properly or quickly. Everything seems to be slowing down. I can’t get in to a new neurologist until the end of April for updated EMGs (upper/lower), nerve conduction studies, and brain MRI. My symptoms seem to be pointing to MS. I have seen different rheumatologists and RA/lupus was ruled out. There are times I suddenly get really hot, sweat or very cold. I ask others around me if they are hot or cold and they aren’t experiencing the same temperature discomfort I am. Excessive heat really bothers me. How were you diagnosed with CIPD? Should I ask my neurologist about CIPD? I seem to have pain, numbness, weakness, etc. all over my body. Thanks!
