I share your bafflement at trying to recall pain, I can't do it to any fidelity either. But I actually think that this is not unique among sensations, and most of our memories are about as hazy as this. I can remember that I did or saw or smelled things, but I can't exactly reproduce the sensations/images. I also have to disagree with the logic of the following: > Maybe it doesn't exist at all, and all it is is an illusion formed by my brain's negative reinforcement signal ('this is bad. Stop doing this'). That would at least explain why it doesn't show up in my memory. It doesn't matter whether pain is an illusion, we can easily recall visual illusions.
