Perhaps view OPs explanation of PAIN as an adjective descriptor since Q uses "double meanings". Multiple meanings don't necessarily negate any or all of those meanings.

I notice Q linked PAIN to TRUTH. For now, I just made a note of that linkage along with OPs data points around the meaning of PAIN I was unaware of. I will muse later or wait to see how things unfold. My presents will determine my choices.

Future events can reveal the accuracy or utility of past guesses.
