maybe... question, what's your trigger? food seizures, photosenitivity, concussion, ect? maybe when you took out the thyroid, everything went haywire. that or the thyroid was protecting something and when you took it out... the seizures started agian. that or when the thyroid was removed, the vagus nerve was messed up or damaged. or something else unrelated to seizures is happing.
i'm just thinking outside of the box. it's probably a side effect from your surgery.

Not sure. I was tested for this late last year.
