I have had a severe cough for over a week. It is persistent and I often go into intense coughing fits that cause me to lose my breath and be very weak. I went to the ER early in the week, at the recommendation of the Nurse-on-Call who heard my cough. I have also been seen by a doctor, and the result of both of these visits is a regimen of Mucinex-D, tessalon pearls, and arithromiacin. I have missed a week of work (I teach) and don t feel I am getting any better. I am light-headed, dizzy, and I continue to cough.
