Those who believe in “psychological pain”, “brain pain”, “conditioned pain”, “pain without nociception” etc., are not realizing that their main premises are based on the appeal to ignorance fallacy. Or in other words - “abscence of evidence is not evidence of abscence”. Just because we cannot identify sources of nociception doesn’t mean they are not there and that the pain is “psychological”. Another implicit assumption they make is to assume that our imaging modalities are finite and are capable of capturing all possible nociceptive states which is far from true.
