Now, imagine a different situation.
A person takes a fall, landing hard on their lower back. Or maybe they lift something heavy and feel a sharp pain shoot down their spine. The pain is severe—they can barely move.
An ambulance is called because no one knows how bad the injury is. Maybe there’s a broken bone. Maybe something in the spine is damaged. And when it comes to the spine, no one takes risks.
I experienced this firsthand. While on vacation in Hawaii with my two kids and my son’s friends, one of the boys slipped and landed hard on his back while getting onto a boat. He screamed in pain.
When we got to the dock, he could barely walk. I had him lie down, checked his legs—everything seemed fine, but he said the pain was unbearable. I was fairly certain—but only fairly—that he had no broken bones and no serious spinal damage. But “pretty sure” is a long way from absolutely sure, and in situations like this, that gap matters.
I could have been cocksure, but confidence without certainty is a dangerous thing. After all, there’s a reason we call overconfident people cocky—because they’re often wrong. I wasn’t about to make that mistake.
So, I did what any cautious person would do: I erred on the side of safety—just in case.
We spent hours in the ER, waiting for a CT scan. Finally, the results came back: normal. No broken bones. No damage to the spine. Nothing concerning.
The good news? By the next morning, my son’s friend was completely fine. The pain vanished as quickly as it had appeared.
But what if it hadn’t?
What if, despite normal scans, the pain had persisted for weeks? Months? Years?
