Seizures caused by abdominal pain?

Has anybody else every experienced a seizure caused by intense abdominal cramping? Every seizure I have ever had, I experienced this prior to the seizure. No doctor has found a reason for this. My first neurologist made the issue very serious and put me on Lamictal. I had no seizures while on Lamictal. My new neurologist (b/c i moved to a different state) thinks i'm just passing out and took me off of seizure medication. I've had three seizures since he took me off(all within a year and a half). My husband has witnessed almost all my seizures and everyone of them has begun with stiffing of my arms and legs followed by convolusion of my entire body. Most of my seizures last 4-5 minutes. Has anybody experienced their seizures being triggered by intense pain?? Does this sound like a seizure disorder or just syncope as my current nuerologist says. Thanks in advance for the feedback!
