I know this is a tad off the subject...but have you found out what your new "Chronic Imaginary Pain" actually is yet?  I'm wondering, because I have RSD/CRPS in the right side of my body.  It started in my foot (after breaking it...it healed fine) amd then moved up my leg, to my hip, my hand/arm/shouler/neck!  I am in "Imaginary Chronic Pain" as well.  However, I have been diagnosed.  Research it...ask your doctor about it.  Getting diagnosed may help significantly in your search for help with managing your pain and help finding the right pain meds for you.  Let me know if this has been any help at all.  Good Luck!
