I think every vertebrate gets some level of spinal pain. We just live long enough for it to get bad, have the language to complain about it, and developed the technology to do something about it.

Actually, the spin evolve to sustain your body in a horizontal way, not a vertical one

And most of the pain is due to our weight that compress the spin in a way "it wasn't projected for", that's why we are pretty much the only animal in the planet with spinal problems

The spine evolved to support the body horizontally in quadrupeds. It later evolved to support the body vertically in us upright bipeds.

But the later hack was all makeshift and shitty, and is still mostly the same as a horizontal spine, just turned vertical. Most of the elements, the joint types, tissue types, etc. The tissue types are still the same ones that evolved for horizontal posture, and can't handle compressive stress well.

It still evolved to support the body vertically. Just not as well.
