Should I see a Neurologist who specializes in PN?

I have PN due to Diabetes 2. I have a neurologist who prescribes med for pain and is sympathetic but does not specialize in PN. In your experience is it worth the time and trouble to seek a neurologist who specializes in PN? My foot pain seems to be getting worse and I am worried about progression. She has never said that it will progress but I have read that it will. Of course I am frightened about winding up in a wheelchair. My mobility now is limited and this week especially bad in the pain department. Please let me know your thoughts. Thank you.
