Hi, You sound just miserable. I agree
with Sara. You have more than the
flu. The
flu (influenza) itself only lasts 10 to 14 days, but you may have developed a pneumonia on top of it. OR it was the flu but was another infection which likely has a severe bronchitis or pneumonia with it - like walking pneumonia.
After a month of bringing up phlegm, you need to see a doctor and probably have a chest X-ray. Please be evaluated!
You are on an MS Forum. Do you have MS also?
