I am a 62 year old female, sedentary because I am going to graduate school. My granddaughter goes to day care and brought a runny nose to my house. I developed a cough that sounds like a "frog" or fog horn. It feels like an itch in my throat and the cough comes on. I have a slight runny nose, but other than feeling a little tired I'm ok. I have tried DayQuil, NiQuil, Tussin DM, Delsym. Nothing is stopping the cough. Could it be a form or pneumonia?
