No diagnosed cause for any of this (i.e. still idopathic), but we've done lots of tests. Blood tests (including a repeat of a couple earlier ones) today and neck/spine MRI on Monday. Diabetes and pre-diabetes is eliminated as a possibility. Fine on B12, etc.

Questions for similar people:

Has anyone else had mostly pain-related PN progress into muscle weaknees?

If so, do they believe they've found the cause and/or what did they do about it?

Did the weakness ever stop progressing?

Thanks, as always.
