Since I am guessing that my persistent visual symptoms began after an episode of nocturnal migraine, I had some questions about them. I am asumming that you can have nocturnal migraines and be completely unaware of them? Is it common after a nocturnal migraine to have a headache or other symptoms after waking up, or can you have a nocturnal migraine without being aware and then wake up without any pain or aura or anything else unusual at all? Also, have you heard of people who only had nocturnal migraines and no migraines with or without aura while awake? I wonder in my case if I suffer from frequent nocturnal migraines but almost never from a migraine with or without aura during the day while awake. Also, is there a way to confirm with a test or something else that you can do to determine if you get nocturnal migraines or if you had one the previous night?
