SYNOPSIS The relevance of side‐locked unilateral pain (with no side shift) in diagnosing and differentiating primary long‐lasting cephalglas such as tension headache and migraine is not clear, In the present study we have retrospectively examined the frequency of side‐locked unilaterality in 1169 primary headache outpatients, whose pain duration was more than four hours. The cases were migraine (66%), tension‐type headache (21%) and non‐classifiable headache and atypical facial pain (not well defined headache) (13%). The occurrence of side‐locked unilateral pain was more frequent in migraine (17%) than tension headache (4%). However side‐locked pain was found to be more frequent in patients with not‐well‐defined head pain (28%). Of the 1169 patients, 181 (15%) had side‐locked unilateral pain: 70% of the 181 had migraine, 25% were not‐well‐defined head pain cases and 5% were tension‐type headache cases. The high percentage of migraine cases in the side‐locked unilateral group reflects the high proportion of migraine patients in the studied population.
