Hemicrania continua: ocular discomfort heralding painful attacks.
It is known that in a minority of patients attacks of hemicrania continua may be accompanied by ipsilateral ocular discomfort. This symptom mostly occurs during exacerbations and is regularly concurrent with the pain. The observations reported here suggest that in hemicrania continua, ocular discomfort may, in rare cases, precede by a considerable length of time the onset of pain. It is postulated that the asynchronous appearance of these clinical features may reflect either an extreme fluctuation of the intensity of the pain or a dissociation of the pain from the ocular discomfort.
