After Eating I Started To Feel Like I Was Choking,

After eating I started to feel like I was choking, however I had no food in my mouth, I think I burped and started coughing so hard that I felt like I couldn't breathe, airway was cut off. I leaned over and tried to calm the cough down and the airway slowly opened back up. I have never smoked. My children and husband were very concerned. THis has happened twice in the last few days.
