What kind of sickness was this?

When I was a teenager I was just hanging out with my brother and playing video games like normal but suddenly I got dizzy and felt sick. So I sat outside to get fresh air. I only got more and more sick and eventually started vomiting. I went into the bathroom to puke repeatedly and I had this weird sensation like my entire torso was going to explode. I can't describe it any way but this sort of "charge" from my neck down to my pelvis. I've never felt anything like it before or since.

For days afterward, I was stuck in this catch-22 where I would have to get up to vomit, but also, getting up would make me extremely dizzy which would induce even more vomiting.

I also couldn't help but walk with this weird gait that made me look like a zombie. My sister said it looked like I was going to go kill someone. I just remember being stuck in this weird position with my hands held slightly in front of me and a soulless expression on my face while I walked to the bathroom or wherever I was going.

It ended after about 5 or 6 days. But I never managed to get to the ER or figure out what was making me sick. It just went away as mysteriously as it came.
