Someone I know recently made a comment about how he feels a sort of pain durring prayer (and that this type of pain only happens during prayer). He says that it used to only be present during confession, but now it is something which has become more permanent.
I'm trying to help him figure out if it is psychosomatic or human (we believe that demonic can be safely ruled out), but I don't know enough about mystic theology to be able to really comment on it. It does seem up that alley though. Is this something which has been documented elsewhere?
