Seizures during GTT?

Ok, I'm new here. Hello guys.
I had a 5 hour GTT today. I've had symptoms of hypoglycemia for a while now, but have had doctor troubles...I have had crashes in doctor's offices, with a sugar reading of 58-59, and they still think I'm just having a panic attack. They put me on a meter for two weeks and the majority of my readings were normal, yet my symptoms were bad.

Anyway. My test was going fine, but about 1/4 of the way through, I started having seizure symptoms....my head started moving back and forth, my arms and hands started waving/flapping, my eyes going back and forth...I thought that maybe I was imagining something, so I tried to calm down. When I figured out I couldn't control it I panicked and the doctor that came in thought I was just having a panic attack. They took a finger prick and my sugar was "ok."

It went away, then an hour later, it started up. This time, I didn't tell the nurses, and I stayed calmer, and in a few minutes would subside. I had about 4 different episodes...the later episodes my lips and my right hand was tingly, my face was twitching, my shoulders and arms twitching, as well as my head and arms (mostly my right arm) were moving back and forth and I couldn't stop it. Never actually lost my bladder, but definitely almost did, and as soon as it went away I had to go to the restroom. I plan on telling the doctor about the other three episodes when I get my results.

What the heck was this, do you think? It scared me pretty good, and now I'm more confused than ever as to what's going on. I have NEVER had this happen before. I'm honestly tired of people thinking I'm just panicking. It has to be more than that.
