I am a 71 year old woman in excellent health (until this winter) and on no medications. I do not smoke. I got a case of influenza mid January and from that developed a bronchial infection. Since then I have had one bout of bronchitis after another. My doctor prescribed antibiotics, which were effective momentarily, but within a few days to a week I would be sick again, with high fever, chills, loss of appetite, loss of weight and chest pains. He has not done any blood work, and tells me there is nothing to worry about, but I am concerned that I might have a more serious condition such as TB
