influenza
"I went to the doctor because I was having chills, high fever, and muscle pain. They tested me and said I got the Flu. They prescribed me Tamiflu but before I left the doctors, they gave me 600mg  of motrin which immediately resolved my fever and muscle pain. Later when I got home I took Tamiflu and the next 2 days I had extreme abdominal cramps. On a scale of 1-10 the pain was a 10, and this was continuous the entire day. I would constantly wake up in the middle of the night due to my abdominal cramps, diarrhea, and vomiting.  I have never felt a worst pain in my life until I took tamiflu. I was way better off without it, the medication was expensive as well."
