More than sick?

Well I talked to Pete on the phone about the Coroners meeting on Thursday and I was telling him about my cold and the symptoms. He said that it sounded like the flu his wife just had. It is a different kind of flu. He said in her it turned into pneumonia quickly. So I looked up the symptoms of pneumonia. Several were similar to what I had, but the one that stuck out was the singular or multiple episodes of teeth-chattering-shivering and feeling cold. I had that on the night I started to feel sick. So I think I could have or do have pneumonia. I don’t know if that is totally correct, but that one symptom seems to go well with the other symptoms.
