Background Hemicrania continua ( HC ) is a primary headache disorder with full response to indomethacin as one of its diagnostic criteria; however, indomethacin's side effects could limit its use in HC . Case Result We report a 33‐year‐old lady whose headache fulfilled the criteria for HC , but the patient developed gastric side effect to indomethacin and did not respond to other pharmacological treatments; however, injecting botulinum toxin type A has led to complete resolution of all of her symptoms.
