5 Minutes Ago I Swallowed A Drink Of Iced Coffee

5 minutes ago I swallowed a drink of iced coffee and it seemed to close my windpipe. I could not breath at all for maybe a minute. Since then it feels like my windpipe is constricted and my breathing was a struggle which has led to fits of coughing. I have asthma and so as soon as I could inhale fully took two puffs from my prescribed inhaler. I am breathing easier but am worried there is more I should do.
