influenza
"On Monday night I started experiencing a runny nose and  feeling kind of dizzy so I decided to go to bed. I woke up the next morning feeling terrible. I was aching the entire day all over my body. I had the chills, sore throat, headache, and a fever of 100.2. I felt like crap so I decided to go to the doctors and they tested me for the flu and it came back positive. I had influenza so my doctor put me on Tamiflu. The first night was the worst, I did eat something hoping the medication would give me no side effects, but I was vomiting and my body was aching so badly. It took me forever to fall asleep but when I woke up the next morning I had no aches and no chills. Each day was better being on Tamiflu."
