Keep blowing your horn about being tested for various hormone deficiencies. I found my pain doc (physiatrist) when he picked me up on his case load when I was put in the local physical rehab hospital 12 years ago. He tested the various levels and found me low in testosterone and several others. Getting that corrected helped the pain somewhat but certainly improved my mood. I was able to go off of antidepressants at that point. I now have complete bloodwork done every three months. Pain patients need a doctor who is current, well read, and has a big bag of tricks.
