Every now and then, I have this strange sensation that comes over my head, it lasts for a few seconds, its been like this for a few weeks, ime not sure if its lightheaded I have felt abit dizzy at times...

But this sensation, would you know what it is, I was looking up brain conditions yesterday to see what it could be, and then this feeling came overme again, is it something to do with Panic? I get nervous aot, I run alot too as training, should I drink more water?

It sometimes happens when Ime running too, its a rally weird horrid feeling that happens for a few seconds you feel like your going to faint...

any ideas thanks guys =] just wondering if u know what it might be

it dont happen that often, but there is some dizziness I have too, I feel this when I come of a bike after riding abit, I feel weird to walk around after using it...

I could only describe the weird sensation like a tingle feeling, its closer enough but its kinda not a tingle feeling like a pressure feeling for a few moments, its real hard to describe

maybe its because i panic sometimes? maybe I need to calm down?
