For a little over a year now I have been having strange episodes that are hard to classify.
It starts with me feeling weak, and like things are moving slow. It gets difficult to talk. Then it feels like all my muscles in my body are shaking and lack strength, but when i look at my hands, i can see that they aren't shaking. But i don't have the strength to stand or hold anything in my hands. Then i get weird vision/scenario superimposed on what i'm actually looking at. then it feels like my heart beat slows way down. It can last a couple minutes no more than 2-3 minutes, usually. Once its over, i have a splitting headache, and it takes a minute to be able to speak and move again. And i'm usually nauseous.
There really seems to be no rhyme or reason to when this happens, except if I haven't slept its more likely to happen. But I could be anywhere, doing anything.
What could this be? What tests should I do? Who should I see?
