I just saw this thread today and read the entire thing, so glad that the dr's response was so good, and glad that Kevin is improving and you are now taking it easy, as it is very true that we moms tend to let ourselves get run down taking care of everyone else. I will say, at least around here, there is a VERY virulent cold virus that moves into terrible bronchitis in almost everyone I know of that has had it (and I know more than 30 people in the last month), and in those who have a higher susceptibility to chest ailments (asthmatics, etc), it seems to go to pneumonia very easily as well. This is what happened to me, and when they initially diagnosed me they put me on Zithromax and the cough syrup with codeine, these did not even touch it, when I went back and saw my actual dr (first visit was to an urgent care), he changed me to the Levaquin and added the steroid, and I started improving almost immediately, however, I am now 6 weeks into this, and still have some cough, which the dr says is that my asthma was aggravated by the pneumonia and it is taking its time calming back down to normal. Also, my sister, who ended up in the hospital with it, was told that taking the cough suppressant during the day would contibute to pushing the bronchitis into a pneumonia, as coughing helps keep it from settling in the lungs. They told her to take the cough syrup at night so she would sleep, but to avoid it during the day. I found that interesting as I had NOT been told the same, she became symptomatic 5 days after me with the fever and headache and cough, and is also asthmatic so is still having SOME issues as well. We are both still fatigued by it, as well, so I would expect Kevin will continue to have fatigue issues for awhile yet, even as he improves. But wanted to reassure you about the Levaquin, as in all but 1 of the many cases I know of, the only thing that even STARTED to work was Levaquin. I do believe that whatever this particular strain is, it is resistant to Amoxicillan and to Zithromax,etc. and is requiring the stronger Levaquin to get relief.
