I ve had a persistent cough (congestion when I lie down) for over 6 weeks and whenever I cough it tastes strong of an almost fruity metallic taste. There is little phlegm if any and no throat ache or anything. Mornings and nights I tend to wheeze constantly. I don t have asthma and am not currently on any meds. Should I be worried?
Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. Nighttime coughing with wheezing in morning and night are seen in1. Asthma2. Bronchitis3.  Early congestive cardiac failure (CCF). So better to get done1. Clinical examination of respiratory system. 2. Chest x-ray. 3. PUT (pulmonary function test). 4. Ecg5. 2d echo. Chest x-ray and PFT are needed to rule out asthma and bronchitis. ECG and 2d echo are needed to rule out cardiac cause. So better to first diagnose yourself and then start appropriate treatment.
