Simultaneously, it exhibited anticipatory serious pain behaviors when their surface was just cleaned just before shot, indicating you to definitely body cleaning repetitively from the venipuncture became a trained stimuli to have causing soreness solutions for the lack of soreness arousal – a good example of trained nocebo answers.
