Other primary headache disorder – http://id.who.int/icd/entity/1350703173
A group of clinically heterogeneous headache disorders, believed to be primary. Although largely unrelated, they fall into four categories: headaches associated with physical exertion; headaches attributed to direct physical but innocuous stimuli; epicranial headaches; and other miscellaneous primary headache disorders.
