Wasn't one with allergy as I live in dry climate of New Mexico, but that has changed. I now get sneezing, post nasal drip and this choking to point of gagging so much to point of vomiting. Here's a couple of things I did. First, went to see allergist but then went to ear, nose, throat specialist who determined that my throat was developing scar tissue from acid reflux. A procedure to done to open throat via a balloon. It was helpful in my swallowing and adjusted diet to avoid acid reflux. Hopefully some of this information is helpful. Good luck.
