I was wondering if anyone has repeated assessments after the initial diagnosis of PN?

My husband was diagnosed with small fibre symmetrical sensory polyneuropathy which progressed to large fibre and some motor. I suspect he also has some autonomic.

I would like him to get a complete/new work up done since it has been 12 years since the initial diagnosis.

He is of the opinion "why bother, there is nothing they can do except help with the pain" - would we be wasting our time to push for a new neurologist appointment?

I wondered if now this has progressed they might be able to pinpoint a cause - it is currently classed as idiopathic.

Thanks, Linda
