Hi welcome to Healthcaremagic
Hi, Dennis do not get worried, even if a small drop of water enters trachea there will be cough
and water will be thrown out... since you does not have such symptoms this shows water is not entered trachea, it is in esophagus
only... if there is breathlessness, severe chest pain
, then you can visit doctor, otherwise not necessary...
Hope I have answered your question..
