I have both MS-choking issues, and throat-closing allergies (especially to mold and feta cheese). I can try to explain the difference between the two, at least for me.
With MS, my choking is like a sudden blocking, like when you choke on water (imagine drowning

). It can happen with or without food and liquids, and most often when I am laying on my back. It makes me cough, but clears reasonably quickly . . . right back to pre-choking status. (I do know of some PwMS who actually end up with something "stuck" 1/2 way down though, but I think this would be a fairly distinct sensation if it happens).
With allergies, it is a slightly slower process, and it feels like my
airway is progressively getting smaller/closing off. I swallow a lot, and get a sense of anxiety (adrenaline??). It is NOT something I can "cough" away, and since it progressively gets worse, I NEED to get at antihistimines (Benadryl) to manage it. When I take them, the sensation lets up fairly quickly.
That's my experience.
