Many cluster headache (CH) patients waited several years to be accurately diagnosed because their symptoms areoften mistaken for sinusitis or a dental disorder.1 Patients have also been mistakenly diagnosed as analgesic drugabusers or suffering from a psychiatric illness. This case report illustrates how a young lady was diagnosed to havecluster headache after several years of consultations with ophthalmologists for eye swelling and redness. It alsohighlights the importance of pain assessment and a general and holistic approach to medical care which is the maindistinguishing feature of Family Medicine.
