Did you consume large amounts of the zinc form back before 2011 or so?

There are over 100 causes of neuropathy, and no we have not had a poster here who was using the old formula so much to get the toxicity.

We are used to hearing that doctors tell the patients, they don't know. One thing though is they typically won't admit another doctor's prescribing drugs that actually cause PN. They stick up for other doctors, or won't tell you if what they gave YOU recently or for a long time caused the neuropathy.

Idiopathic is the medical term for "they don't know".
If you visit our subform here on this location, there are informational posts to explain neuropathy in more detail. Many doctors just have no clue.
