Neuropathy has many causes and symptoms. A primary one is diabetes (which I don't have). Considering the rapid onset after starting Jardience, have the doctors checked for interactions with other meds or tried switching to a different medicine? My symptoms are mostly loss of feeling in my hands and feet that is progressing slowly. I've had polyneuoropathy for around 10 years and it hasn't impacted me much (yet). I try to slow the progression through diet and exercize. If you have a medical background you can look for research papers on ResearchGate or Fed. Govt sites (all NIH-funded papers are online now). There are so many autoimmune diseases, and most doctors don't have much knowledge about them and their complex presentations.
