Pain from coughing up water after laughing cannot inhale all the way through and is having a hard time breathing what can I do?

Difficulty breathing. Likely reactive spasm to aspiration of water but difficulty breathing is serious and should be addressed by 911 and EMTs./ ER. Call 911( do not go by personal car if difficulty breathing- only 911 ) now they can give you a breathing treatment and take you to ER for definitive treatment.
