It hasn't helped me but then I only have numbness with my neuropathy. I've read a lot saying not to drink it close to bedtime but I did come across this interesting article from 2016.

The Role of Caffeine in Pain Management: A Brief Literature Review: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5018099/

I do sometimes drink a cup of coffee in the evening but not right at bedtime because it does tend to make it harder for me to fall asleep. Hopefully someone who has found it helpful can share their experience.
