Make sure to check back for replies on your post because I have a feeling there will be many who relate to broken nights, sleepless with pain. Whenever I have something going on it seems pain is more intense during the night. I've been told it's because there's nothing to distract my mind at night.

I'm sorry you haven't found any answers about what's causing your pain. That's why it's good that you posted a question; it can feel self-negating to look for answers and find none. I'm sorry you have been through this a long time.

For the past 2 years I've had severe lower back pain. One of the things that I do, rather than getting up, I leave the heating pad plugged in by my bed. I can reach over and use it for 20 minutes and I get some relief. It's things like that others might add to the conversation.
