question: Hello, I believe I recently came down with the flu as it started suddenly with a sore throat and body aches through the upper back and neck . Spent yesterday with a mild fever and lots of coughing. I am an asthmatic so the added inflammation in my bronchial passageways is less than pleasant to say the least. Today I feel like I am on the up&up and the cough is no longer producing white sputum , but when I cough hard there is a metallic-type taste in my mouth. I figured it s normal since I spent the better part of 48 hours, day and night, hacking my lungs out. Anyway, is this normal or something to be concerned about? Thanks so much! -Jonathon
