I have had a persistent cough for about 10 days now. Very little sputum produced with this cough. I've have 2 nodules in my left lung that Drs have been watching for 2 years now. We are snow birds in live in the CAve Creek , AZ for the winter months. Otherwise we farm in Montana. I do get night sweats but no fever and feel fatigued. Coughing wears me our and wears me out. About 2 months ago I was put on 20 mg of prednisone for a bulging disk that was causing sciatica which I took for 4 weeks. After I stopped the prednisone I got a severe sinus infection and flu symptoms. Got better but this cough won't go away and has gotten worse. Wondering if this is Valley Fever? Collette Neuman
