For as long as I can remember I've had what I can only describe as 'brain zaps' it feels like a zap, a bolt in my brain which shakes it, it makes my eyes shake for a second when it happens and then I'm fine.
When I was younger I only ever got these when I was ill so I just thought it was a normal part of being ill.
As I've gotten older (30 now) they happen when I'm ill but also they happen once in a while when I'm feeling fine.
I remember being about 20 and walking over a bridge and there was a pattern on the bridge and looking at this pattern would cause the brain zap and eyes to shake, not just once but every time I looked at it as I was walking.
Also when I would frequence clubs a few times I had to go outside as I felt the zap due to the lighting and would feel my body tense up but I wouldn't actually seizure.
What has worried me is the other day I was driving and the sun was coming in and out the trees if you know what I mean. So it was shining in my eyes then would be a shadow then sun in eyes then shadow at a fast speed and I had the same sensation a few times in a row. The the point I had to hold my hand up to block it and was panicking that I was going to pass out.
Does this sound like something serious? It really doesn't impact my life at all other than it's a weird/unpleasant sensation, however, happening when driving has worried me.
