Facet Joint Pain-lumbar

[Tableone]

Could someone please tell me what facet pain feels like? I need to know if lumbar facet pain causes a deep achy bone pain or does it cause a nerve pain. Everything on the web is vague.

Also, after several months of research, I think I've finally figured out that when general literature says "low back pain" they are referring to achy bone pain and when they mean nerve pain they say "nerve pain," or "radicular nerve pain." I am correct here? Please let me know.

thanks!
