Once in a while I get something which initially feels just like it's a big head-rush. I get really dizzy and start shaking, at which point I usually let myself down onto the floor, or lean on whatever's nearby so I don't fall, and I don't know, it's like some sort of light convulsing. My vision goes blurry, and I'm aware, but not 100% aware of what's going on. Sometimes I don't get it for about a month or more, but sometimes I get it a few times in one day. It lasts roughly 10-20 seconds I think. I'm 16, I used to smoke, but I quit about a year ago, I'm female, I'm quite thin, and as far as I know I don't have any medical issues. And no, I'm not looking for a diagnosis, just some sort of idea about what's going on. Tell me to go to the doctor if you really think I need to, but please also tell me if you have an idea about what's going on. Mostly because I really don't like the idea of going to the doctor.
I haven't really noticed much of a pattern in it, but I think it happens more often when it's hot, though not always.
Thanks x
