@antonintampfl2009 and @mikead63 To be honest, I've always thought of the neuropathy progression as a sliding scale and not any specific stages - like bad, worse, and worst. None of the medical resources I've seen mention specific stages like 1, 2, 3, 4 but a search shows different medical facilities/clinics that treat neuropathy provide a list of stages. To me it still boils down to doing what you can to prevent the progression of the condition through whatever means works for you - supplements, diets, lifestyle, exercise, medications, therapies, etc..

Here's just one of many references on the stages - https://ethoshealthgroup.com/5-stages-of-neuropathy/.
