What causes fevers, chills, night sweats resolving into cough?
My spouse developed high fever, chills, decreased appetite, fatigue, achy joints, and mild diarrhea. Two days later, I developed the same symptoms with fevers, chills, rigors, night sweats, decreased appetite, and very mild bowel symptoms.
Neither of us have had flu shots, so we assumed it was the flu. Our kids, who did have the shot, did not seem to get the illness. The above symptoms lasted 4-6 days for both of us during which time we were laid up in bed.
As the initial illness got better, my wife began to develop a sore throat and cough. She also developed wheezes and crackles in her lungs (no need for a stethoscope to hear those!). She was only coughing up clear spit – nothing green. As my illness got better, I followed suit (no sore throat though, but cough) and now as I breath in and out I can hear my lungs sputtering and popping. I haven’t coughed up anything green, but I did just cough up something (very small, maybe 10mmx3mm) that looked like a small bit of lung tissue.
Only during the initial illness did either of us have fever. Neither of us have fever now, and other than the cough and junky lungs, we feel fine.
I haven’t really heard of any lung illnesses that start off so bad with fever/chills but then leave a person with such a terrible cough and junky lungs and no other symptoms (fever). I would assume that pneumonia and fever always go hand-in-hand, so if our initial illness was some kind of viral/bacterial pneumonia (instead of the flu), shouldn’t we still have a fever?
What are the possible causes in this case?

Sounds like an infection to me. And no, a fever doesn’t have to be present to have a bad cough and junky lungs. Why would you want to create more symptoms? The fact is, you are both suffering from a respiratory illness. If if persists, consult your doctor.
your body has a Ph balance ……. if you are acidic in Ph, you will be ill …. you need to get your Ph up to a level of about 7.4 to 7.6 to be well …
simply eating fruit is a way to do this ….. like oranges … grapefruit … things like that …..
Approx. 10 years ago, I experienced the same symptoms as you after 3 months of moving into a new region. I moved from Houston TX to the Cental Valley of California. We attributed it to the toxic agricultural area. I’ve never experienced such a severe illness since.
Now, I don’t know what your circumstances are that may have attributed to your illness, however, you do have, more-than-likely a bacterial infection. Once the airways began to dilate you will then be able to move retained secretions which will be discolored. Do not be alarmed, but grateful. However, if you cough up blood then its off to the doctor you go, quick! Stay hydrated, get your nutrients and rest.
HTH! Speedy recovery to you both.
