The following are resources for neuropathic pain control.
A great phone app with interactive instruction and psychological techniques for managing pain.
This is a fantastic book that explains how pain works in your body, central nervous system, and brain. The audiobook version is even better yet as the book was co-authored by two Australian neurologists, and the authors engage in a friendly audible discussion. Understanding how pain works is very helpful in understanding how to manage it. This book is not inexpensive; the audiobook is probably more affordable, but it might need to be purchased directly from the author's website.

UCSF Pain Management Center
University of California, San Francisco has psychologists who specialize in pain management, and they understand people with MS. Your first appointment might be required to be made in person, so it might be a big commitment to make it to downtown San Francisco (next to the UCSF Hospital). Subsequent appointments can be made by telemedicine. They take health insurance.
