So you have any symptoms of TIAs?

I had symptom of one every 6 months or so since high school. Got exposed to some chemicals and it went to a couple per week.

Blood thinners keep it under control.

I got hospitalized once with the suspicion of having TIA but it turned out to be migraine with aura. I had those since I was a kid but never so intense (part of vision going poof!). I identified that the trigger is intensive smells (like vinegar for example).
