I have had a cough for many years which doesn t seem to have a cause anyone can find. My husband notices that I often get a coughing spell when I first begin to talk - like after meeting someone or to him after having been quiet for a while. He thinks that mucus draining from my sinus cavity builds up over the epiglottis which doesn t close tightly, thus allowing small amounts of fluid to seep through into the trachea. Is this a possibility?
