Hmm I have had that feeling when I have like a panic attack, but not my usual one. I can say that because I fan my hands at my head.
Now on the other hand my husbad gets thehot ears and neck when he is REALLY tired. They go red and hot. Hehe its one of the ways I know he is tired even if he doesn't say so.
Do you have any allergies that you know of? I also get that numb throat, tingling tongue if I eat tomatoes, pineapple, creamy goat cheese and sometimes bananas.
Wish I could say for sure but these are the things where I have seen it happen. Hope you are feeling better now
