Had sudden attack of dry, itchy feeling in nostril and back of throat, which made cough and gag. I could not stop it, tried gargling , took benadryl, it is calmer now but i have to keep sucking on longezes. I am on 5mg prednisone/day for autoimmune . What do you think? Also am recovering from chest wall contusion, its been two weeks, but coughing is not good for me right now.
