Sometimes if you get a minor irritant in your bronchial tubes they will spasm and close up. I get this if I accidentally aspirate a tiny drop of saliva, for example. The way I deal with it is to focus intently on my breathing and slow it down, then focus on relaxing my throat. It usually takes a minute or two.
I'm sorry this happened to you!
