@mjf - I've heard of ablation for neuropathy but haven't read much about it. Here is a discussion from 2017 that discusses the topic and may answer some questions you have:
-- Experience with Radio Frequency Ablation procedures?: https://connect.mayoclinic.org/discussion/experience-with-radio-frequency-ablation-procedures/

Mayo Clinic has some information here - Radiofrequency neurotomy: https://www.mayoclinic.org/tests-procedures/radiofrequency-neurotomy/about/pac-20394931

Have you discussed it with your doctor or care team? Wondering if they had any thoughts on if it would help.
