I can certainly relate. I've been fighting this spinal pain for more than 27 years now, and I'm just so tired. Totally exhausted, ya know?
After you've had chronic pain for a long time, the pain receptors go haywire, and they send pain signals even when there isn't any pain! So you HAVE pain even when there isn't a REASON for it. My MRI shows plenty of reason for it, but the pain receptors might be adding to it -- who knows? All I know is that there are days I can barely move.
I feel so bad for the people who are in worse shape than I am, because I cannot imagine what they're going thru. My heart goes out to them.

There are people in wheelchairs, etc. And I can still walk, albeit a little strange. LOL
I wish you all better days, and days of healing. God bless you all, and I hope you can find pain relief somehow. Take care! Hugs, Lee
