Influenza
"I began having flu symptoms at work  2 afternoons ago -fever, chills, achiness. I went directly to an urgent care clinic. The flu test was negative, but the physician&#039;s assistant said I had come in so quickly that I probably wouldn&#039;t test positive yet. Based on my symptoms and the current flu outbreak in our area, she prescribed Tamiflu. 
That night, my fever broke in the middle of the night. When I had the flu before, the fever would return in the evenings, but I&#039;ve had no more fever and chills. Also no achiness, just fatigue. The only side-effect I experienced from the Tamiflu was moderate diarrhea. 
Much better than being sick for a week or two.l!"
