Mel,
There is no published study or hard evidence
that relates neuropathy to smoking - none whatsoever !
Probably because no study has ever been done, relating smoking & PN.
All the docs say stop, but that is general in preventative measures or because of existent problems.
I am scheduled for a CT of my chest in Jan, because an x-ray of my chest earlier this month showed evidence of my 45+ yrs of smoking. I know I'm gonna haveta stop in the near future, because my doc said emphysema was showing on the x-ray.
I thought it was bronchitis, but now I know its all (COPD ??) related.
