I don't think it is unimportant at all. This pain sounds like it's really affecting you. For me, I need to work on emotional pain first, because sometimes that is linked with physical pain and when I address it some of the physical pain goes away. Like I had really bad pain in my arms, I couldn't even open doors, and then when I addressed my depression, most of it went away. It was crazy. Not saying that would necessarily happen, but like, maybe some of the physical pain is linked. I'm assuming you've done physical therapy? Have you checked with a physical therapist? That might be another thing to pursue at the same time. Just my two cents.

Edit: I have also had chronic jaw pain, and it was important with that to address them at the same time, since I couldn't really eat. Having trouble walking is clearly affecting your quality of life so getting at emotional and physical at the same time might be better.
