Introduction: Hemicrania continua (HC) is an uncommon primary headache disorder which clinically is considered a syndrome with two pivotal characteristics: strictly and steady unilateral headache, and absolute response to indomethacin. Primary cough headache is an uncommon headache disorder as well, and has a good response to indomethacin. Case report: We report a case of a 71-year-old woman with hemicrania continua and primary cough headache who had an absolute response to indomethacin. Conclusion: Hemicrania continua has an absolute response to indomethacin, and this fact is fundamental to the correct diagnose. Primary cough headache may have an absolute response to this drug as well. To our knowledge, this is the first case of hemicrania continua and primary cough headache in the same patient.
