CH without pain? in General Board Posted August 20, 2019 · Report reply The attack you experienced sure sounds like CH. One difference between migraine and CH is that while people with migraine often seek relief by lying down in a dark room, people with CH generally can't sit or lay still: they are "restless" or "agitated." A proportion of people with CH also have migraine-like symptoms, including aura, so those symptoms don't rule out CH. There are people whose treated CH appears with a feeling that there should be pain, but there isn't any. This seems to most often be true of people who are treating their CH with psychedelic substances. I don't know how it would happen with untreated CH.
