Laryngospasm

I recently had a bout with Influenza A (despite getting the flu vaccine) which was pretty severe; about the second or third day, I began having episodes of "choking" in which my throat suddenly closed up, keeping me from breathing in (at all, at first; then I could with stridor; it resolved after a minute or two). With  research on the internet, I determined this was laryngospasm or an involuntary sudden muscular contraction of the vocal chords. I read in one article that it could be related to the flu in that this virus can actually "denude" the outer tissues of the laryngx, making it sensitive.  Because I never had this before and haven't had it since (only when I had the flu), I tend to believe this theory and attribute it to Influenza A (rather than think it's a vocal chord dysfunction).  Should I look into it further?  Thanks for any insight you can shed on this mystery.
