To compare the presence of allodynia, pain catastrophizing, and the impact of headaches on patients with cluster headache (CH) and healthy individuals. Our second aim was to analyze the relationship between catastrophism, psychological comorbidities, and the impact in CH. ⋯ Our findings reveal significant differences regarding allodynia, pain catastrophism, and impact in CH group compared with controls. We found a significant relationship between psychological comorbidity, pain catastrophism, and quality of life in CH patients. Anxiety and HIT-6 were a predictor (adjusted R2 = 52%) of pain catastrophism. Screening for these comorbidities should be implemented through a multidisciplinary approach.
