Hello. I am a 22-year-old female with a younger brother who suffers from petit mal seizures. Since around the time I hit puberty (13), I would occasionally (every one to two weeks) suffer sudden boughts of dizziness and tingling in my head and extremities, usually prompting me to grab onto something for support so that I wouldn't fall, as my legs would immediately go numb.

As I've gotten older, I've noticed that during these episodes my movements have become more sluggish and difficult to control - more often I have to simply sit down wherever I am because I don't have enough time to grab onto something for support. Recently I suffered an especially severe attack where I fell down without any warning and my hands and feet began to twitch uncontrollably. Afterwards I was very tired, which has never been the case before.

I doubt that these are seizures, or at least certainly not any kind I have had any personal experience with, as I remain consciously aware the entire time. In fact I might never have even worried about these episodes at all if it weren't for the fact that the symptoms suddenly seem to be escalating in severity.

I haven't been able to find anything specifically related to my situation, so I was wondering if anyone here could shed some light on what my problem might be. Am I worrying over nothing? I used to think that it might just be blood rushing to my head, prompting the dizziness, but now I'm not sure what to think.
