Lower back pain is distinct from pain in other joints due to the larger, more powerful muscles involved that are prone to significant spasms.

“No, it's different. I mean, the best analogy is I sprain my wrist, you know, I might have to wear a brace or something, but I can generally function. I can go to a movie, but when your ribs or your back is hurting, not only are those muscles much more big and powerful, so when they react and spasm, they're really good at it, right? Like these small muscles in my wrist, when they react in spasm, you're like, "Oh, that's kind of sore." But the low back, I mean, that group of muscles is really good at freaking out, right?”
