Headache Attributed to Temporomandibular Disorder and Primary Cough Headache

Abstract

Orofacial pain is a frequent chief complaint of many systemic disorders. A primary cough headache may mimic the clinical symptoms of a temporomandibular disorder (TMD) or may be associated with TMDs. Case report: A 52-year-old man presented with a 1-year history of TMD symptoms with clicking. He presented with the chief complaint of a sudden and severe headache when coughing, sneezing, or crouching. Comprehensive intra- and extra-oral examinations were performed, which revealed myofascial pain involving the right masseter and temporalis muscles, disc displacement with reduction in the right temporomandibular joint, and headache attributed to TMD, but no severe headaches appeared in the cough-induced test at the first visit. Initially, we advised the patient to minimize activities that require jaw function (e.g., chewing), avoid jaw parafunction (e.g., bruxism), and to perform at-home jaw exercises to stretch the jaw muscles. The patient’s symptoms reduced by more than half after the TMD home care and physiotherapy. He was then treated with 75 mg of indomethacin per day, which eliminated his headache. The patient was then referred to a headache specialist, who diagnosed primary cough headache.
