Does anyone get painful shooting sensations, a bit like electric shocks in their head? I think they might be related to some sort of trauma reaction as they started as frequent fear sensations, like a rush of adrenaline sensation that you get when you witness something bad about to happen, but then at some point they were almost constant and turned into rushes of pain/shooting pains into my head. I've had them for years, no doctor has a clue what I'm talking about.
