I have had a nonproductive cough, inspiratory and expiratory wheezes in bilateral upper lobes, major fatigue, and shortness of breath with exertion (including coughing fits) for a week. The ED gave me an albuterol inhaler, tessalon pearls, cough med. with codeine, and Tamiflu. I have had minimal improvement with these. I am staying well hydrated and getting lots of rest. Chest Xray and CT angio were negative. All other labs were normal. ECG showed a LBBB but I don t see how that would relate to my symptoms. No history of lung problems. Am I missing something or do I just need to be patient and wait it out?
