I am a 29 year old male, in generally healthy condition. I ve had slight allergy problems from childhood involving pollen and the outdoors, but nothing that directly effected my breathing. over the last 5 years or so, ive noticed that occasionally when i sneeze, immediately following it feels like my throat closes up and i cant breathe for about 5 seconds or so, maybe longer. it almost feels like im being strangled. my eyes will water and ill gasp for air. its generally unpleasant. i was curious as to what might be the cause of this, if its an allergic reaction to something or some kind of disorder.
