On Monday September 12th I had 20 teeth extracted surgically, I was under general anesthesia for this. By that weekend following, I had picked up a cold from a coworker that had me down for 3 days. Once the worst of that was over, I have had a persistant cough. Called my doctor that following week, they put me on tessalon pearls. That did not work. I went in to see the doctor and they put me on a week of Prednisone, two 40mg tablets daily for 5 days. That did not work either, I then was told to try Allegra, I had already tried Zyrtec and Clariton with no relief. I went yesterday got a chest xray and it was clear. This cough is horrible. Its almost as if I am producing too much saliva or something cause if/when I cough anything up its very thin and clear. Nothing discolored. Please help!
