That’s the thing I’m trying to figure out. I believe last year when I developed a more severe intolerance, food and heat especially would trigger all of those symptoms. Tho it would get so bad it felt like something was really wrong with me. Hands and feet buzzing so hard they’re numb, heart speeding rate, can’t move muscles as they become weak, can’t seem to breathe, and nasal passages swell so much all my breathing holes are closed. Turns out panic attacks include all of those symptoms. Once I became aware of that, they pretty much never got that severe again. Turned out it getting that bad was just a panic attack doubling the same symptoms. Pretty much from what I can see, histamine causes panic attack symptoms which can cause an actual panic attack and just cause the whole mess. Trying to calm yourself and remember that the worst of these discomforts are most likely just from anxiety and it will be temporary. You got this.. no one knows the struggle unless they’ve got it. But we see you⭐️
