Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
I had a cold a few weeks ago which then became a probable upper respiratory tract infection. Since then, I have been having mainly just a cough, coughing up mucus on occasion. However, when I get the coughing fits, I tend to get light headed to the point I almost pass out or slightly black out for a few seconds. What could this be?
