I have had a cough now going on about two weeks. It started out a dry cough that has turned into the most irritating cough with flem. I will have such severe coughing attacks especially when I lay down. I cant seem to catch my breath during my coughing spells either, and it gets to the point where I am gagging. My husband also has this same cough as well as another family member that does not live with us. I thought that it might be Whooping Cough but am not sure. My three year old had a severe cough for about four days but them it went away and has not returned. Does anyone have any suggestions as to what this might be?
