We don't need a simple mutation. Learned associations and mental activity is quite enough for generating or suppressing pain. People can be terrified and panicked at the presence of particular people, pain can be controlled by hypnosis, or caused by phantom limbs. Is there a mutation, simple or complex, for phantom limbs? If I beat my dog brutally every day, does he need mutations to experience pain and stress at my approach?
I don't understand what this is about now. I understand in this fragment you are discussing why can't we make pain go completely away at will, and why didn't evolution invent such a thing. Among the causes you don't consider is this not being beneficiary overall, or not being "a simple mutation away" at any point of our evolution so far, both of which are perfectly feasible explanations.
