Is There a Doctor on the Plane?

Just an interesting observation during my recent plane travels. Soon after takeoff I noted that the everpresent neuro background pain in my hands and wrists was all but eliminated. And remained gone for the duration of the flight. It returned shortly after landing but I got to wondering if altitude or cabin pressure or something else entirely produced the palliative effect. The voice of reason in my head is saying that clearly I need to spend more time flying to remote vacation spots. For my health and well-being. I'm working on a fully fleshed-out rationalization.
