Last Night I Was Eating Some Crackers Then All Of

last night I was eating some crackers then all of the sudden I heard my throat popped then my face turned pale then cold sweat. I thought I was going to pass out. I went to ER, 2 1/2 hrs later, a nurse practitioner told me to open my mouth, hold my tongue with a stick. she said since she didn't see any broken bones and I can breath and talk I should be fine?!?!? if I still have any concern I should go see a Ear and nose specialist. my throat still hurts. I would like to know why my throat popped like I broke my bones (I have broken many bones in my life, so I know the sounds), why I cold sweat, turned pale, ready to pass out..... "I don't know how to explain it" from someone who works in the medical field is not good enough for me. should I go see a specialist or will it be a waist of my time and money again?
