not a radiologist or doctor but...

X-rays show only hard tissue (meaning bone), spacing and some other things. they're limited in the scope of diagnosing injuries and pain syndromes. they do, however, tell a provider what it's not; as in, "no fracture" nothing broken". So on to the next level of diagnostic tools available. If problems persist maybe an MRI or an EMG/NCV.

As far as my understanding, you have a lot of aging/arthritis/degeneration in your lumbar spine, your lower back. a lot...

Endplate spurring and degenerative disc disease (DDD); that is, a finding for pre-existing conditions in your lumbar spine. If you didn't have problems, you were lucky. If you're having more now, you were predisposed to have problems if you became injured in that area.

Your healing could be compromised because of your pre-existing conditions.

With so many levels in your lumbar region, you probably have it in other joints of your body as well.

Smokers and coffee and cola drinkers can have accelerated aging processes also. weight is also a factor, so is past history and work experience.

Get some good treatment and try to limit narcotics, if at all possible. They're not a cure. Just an ugly bandaid that don't work for the long haul. See how it goes. You're going to hurt if you're injured. Sorry you're having pain. Understanding is a big help. Hopefully you'll heal quickly and you won't have chronic problems.
