Hi @jeffrapp I agree with the term idiopathic. To me, a doctor may not know the cause but it doesn’t mean that a patient can not think back to determine potential causes through the process of elimination. It is similar to having an allergic reaction which I never had up until recently. Within a week I found the culprit. I did not waste time going to doctors for questions I can ask myself.
Neuropathy caused by a vitamin B12 deficiency can become permanent if not treated early. In my case, my neuropathy was the result of the last surgical repair for my ruptured AVM. It was a circulation issue involving the embolization of blood vessels. I have learned to deal with it. Luckily, it has only affected the left side of my body from head to toe. I have found supplements that help with the burning pain. The pain differs day to day. I feel we all do the best we can with our ailments(we know our limitations) so we can remain somewhat independent. Toni
