Degenerative Disc Disease
Correlation doesn’t imply causation. It’s a commonly expressed caution in the health sciences. What it means is that two things can tend to go together without necessarily causing each other.
It’s common to be upset when you’ve been told that you have degenerative disc disease. It’s an awful sounding diagnosis. It sounds like you have a disease that is deteriorating your spine. And on top of it all, it doesn’t sound like there’s much you can do about it. The spine, it seems, is inevitably degenerating.
