This is great, @cookierockwell. I hadn't seen this before. It looks like it may have been created by Florida Surgery consultants, so I wanted to link to the original source, which also includes more explanation in the blog post:
- The Pain Scale of Back Pain https://www.floridasurgeryconsultants.com/the-pain-scale-of-back-pain/

I think other members will find this useful too.

The typical 1-10 pain scale often falls short for patients. Who's to say that my 5 would match the 5 of my doctor. This helps to describe the abilities (or lack thereof) with this additional descriptors.
Cookie, how has this improved communication between you and your providers?
