influenza
"I am in my 20's and deteriorated rapidly over a day coughing terribly, joint aches, migraine, very high fever that I couldn't get down with anything while feeling cold and shaking amongst other symptoms. After being up most of the night I went to the doctor and was told it's the flu - tested as well. I was prescribed tamiflu and it's already helping me so much my fever is much more manageable and although I'm still very sick I was able to sleep all night without severe temperature changes. I also suffer from chronic nausea and I know this medicine can make you feel nauseous, but I have had no problems with it at all (I am surprised). I would certainly recommend this treatment if you catch it in time."
