You have tried many ways to handle to your chronic symptoms, and are still hopeful to find suggestions for your path forward. That's inspiring!

My suggestion for you is to take a moment and watch Dr. Sletten from the Mayo Clinic, Jacksonville, explain central sensitization syndrome (CSS). He teaches at Mayo's Pain Rehabilitation Center (PRC), and he and his team do an incredible job.

I'm hopeful that you find a pain management "team". Through my past experiences, I never had a team or group effort that was collectively trying to improve my quality of life, given my circumstances. I benefited greatly from PRC's comprehensive, all inclusive approach on teaching me how to live my best possible life with quality. I gained independence and confidence back, and felt like I was in charge of my well being again.
