Temporary Relief Does Not Explain Why It Happened
Relief is an experience. An explanation for relief is a claim about why that experience changed. Those are different things.
A person may relax, meditate, breathe differently, shift attention, change posture, take medication, rest, or simply wait—and notice that pain changes. They can truthfully say, 'The pain eased,' without yet knowing exactly what caused the relief.
The relief may be temporary. The underlying injury or condition may still be present. Even a repeated association may need testing before it becomes a reliable explanation.
Personal experimentation can outrun evidence when we experience a change and immediately build a theory around it. Some theories prove useful; others do not. Pain still deserves appropriate medical evaluation when needed, and relief does not prove an injury has healed.
Notice the relief. Do not make the explanation more certain than the evidence allows.
