Any body had this symptom?

Ok, here I am again with another scary symptom. Does any body have or had this symptom? Is the feeling like your throat closes for one second either when just sitting,walking,even when talking, this feeling makes me feel like short of breath for a second especially when it comes while I'm talking. Please share with me if you've had this symptom, how long did it lasted and when did you notice it came the most. Forgot to mention that this symptom doesn't stay it comes and goes trough out the day.
