Here is a situation that makes no sense to the person living it.

The injury happened two years ago. It healed. Scans are unremarkable. Every professional who has looked at it has said the tissue is fine.

And it still hurts.

Which leaves people in an impossible position. Either the doctors have missed something, or the pain is imaginary. Neither feels right, and neither is correct.

There is a third explanation, it is well established, and almost nobody has it explained to them.
