The temporal behaviour of migraine related neck pain does not inform on the origin of neck pain: An observational study

Clinicians seek to identify associations between pain behaviours to understand if symptoms are related or separate conditions. This study determined whether the temporal behaviour of migraine related neck pain related to i) the presence of cervical musculoskeletal function or ii) migraine hypersensitivity.Cross-sectional study of migraineurs with neck pain (n = 110). Participants reported daily for one month via an online survey, on migraine and other headaches, neck symptoms, location of onset and self-identified triggers. Allodynia Symptom Checklist (ASC12), Pressure pain thresholds (PPTs), and presence or absence of cervical musculoskeletal dysfunction were also assessed.The temporal behaviours of neck pain in 92 participants (46 migraine only, 46 migraine plus another headache) were categorised as: i) ictal only (n = 42), ii) ictal and infrequent interictal (n = 26), iii) ictal and frequent interictal (n = 17), and iv) undecipherable (n = 7). Cervical musculoskeletal dysfunction was present in 43%. Temporal behaviours of neck pain were not associated with cervical musculoskeletal dysfunction (p = 1.00 and 0.21), nor related to ASC12, PPTs, headache triggers, neck pain, nor region of symptom onset, whether migraine only or migraine and another headache was reported (p = 0.29 to 0.97).Individuals with migraine present with varied behaviours of neck pain in relation to the headache. As temporal behaviour is not informative, a physical examination is needed to negate or confirm a cervical source of neck pain in migraine.
