Two of our grandkids had it, and one developed pnemonia. A few days in the hospital cleared it up. My husband and I had the following symptoms that spanned over a three week period: started as a sinus headache for a few days, then became a head cold for a few days, then developed fever, chills, body aches, dizziness, confusion, extreme fatigue, and a chest cold. Now that we're a few weeks past the worst, we both still have a chronic cough, feeling hot and cold and fatigue. This thing has really kicked our asses! Now I have a sore throat and ear infection...doctor said it is strep.
Our doctor said yesterday that we should've used Tamiflu with the onset of symptoms, and the flu would've only lasted two or three days. So, if you start feeling sick, use the Tamiflu. I sure wish we would've!
