A patient with Fibromyalgia and Chronic Recurrent Multifocal Osteomyelitis: the importance of psychosomatic assessment.

Background: Many patients affected by FM present different comorbidities, but to date no case of FM in patients with CRMO has been reported in literature. Several studies show the importance of psychosomatic assessment in FM, but only one reported the presence of allostatic overload.

Case Presentation: In April 2022, a 21-year-old female patient, a third-year medical student, came to our clinic to be assessed and treated for FM. She presents with a diagnosis of CRMO made in 2014 and a diagnosis of FM made in 2019.

Results: At the psychiatric evaluation she presented symptoms of anxiety, depression, insomnia and reported widespread pain with the presence of almost daily headaches. From the psychosomatic point of view using DCPR-revised she presented diagnostic criteria for allostatic overload, related to study and periodic flare-ups of painful symptoms due to CRMO, persistent somatization, with musculoskeletal and gastroenterological symptoms, demoralization and type A behaviour.

Conclusion: This case shows how useful a psychosomatic assessment of the patient can be for offering insights into what stressors at the origin of allostatic overload may be present in different FM patients.
