My auras/seizures are triggered by eating Free Glutamate and I haven’t found an explanation?? TW for severe symptoms
(Sort of a repost from the main FND sub but reworded slightly)
So for context I was diagnosed with FND after getting an unexplained stomach bug following withdrawal from a heavy cocodamol and thc edible habit in mid 2025 that ended with me losing 30lbs and being unable to eat most foods. About 6 weeks into starvation my “tremors” randomly developed into full body convulsions and uncontrollable jerks, vocalisations, tics, auras and hallucinations etc. Haven’t ever been offered an EEG, MRI or any testing but it seems like it’s off the table since my symptoms don’t seem consistent with epilepsy according to docs. Blood work was all normal at the time except slightly raised inflammation markers that were supposedly related to the stomach bug.
Anyway from doing my own research I’ve found out that my symptoms only happen in the hour after I eat a food that’s high in free glutamate (so MSG, soy sauce, tomato paste, mushrooms, spinach, essentially hundreds and hundreds of everyday foods and additives I’m no longer able to eat). Basically all the stuff that has umami flavour it seems. Even accidentally eating a few mustard seeds in a sandwich or a single piece of chocolate will set me off into multiple days of feeling as if each side of my brain is disconnected and that one eye is higher than the other/one side of my body is bigger than the other and severe sensory disturbances, Tourettes style tics and vocalisations and seizures like that. It somehow feels like I’m having some kind of migraine with shock like jerks where I feel as if I’m being pulled out of my body for a split second qnd my vision falters. This has been getting worse over time to the point where after a year the tiniest amount of tomato paste or canned tuna will trigger head pressure and feeling like fireworks are going off behind my eyes after 20 minutes and then the involuntary movements start.
Weirdly, the things that can help to abort these episodes temporarily (for the duration the drugs work) are ibuprofen and paracetamol?
My neurology registrar (have never been able to see a neurologist on the NHS because of the functional label) thinks it’s something to do with a gaba/glutamate issue but in all of the literature and even forums about FND I’ve never seen a single person say they have the same issue. I’m at my wits end at this point because there seems to be nothing to do other than avoid hundreds of foods and never be able to eat at a restaurant again lol.
I guess I’m wondering if anybody else has anything like this issue?
