I suffer with severe chronic migraines and there are some points during the day when I have a really bad migraine that I'll forget something I did less than a minute ago. Like turning the brightness up on my TV (I turn it down when I have a bad pain or at night). I'll turn it up, do something or think about something and then 20 seconds later I'll try to turn it up again and realise I already have. Does this happen to anyone else? Is it something to worry about? The part I'm worried about is that I have absolutely no recollection of doing it, when it happened less than a minute ago. There's also times I'll be talking to my mum, bring a topic up and then a while later, bring up the same topic and not remember talking about it.
