How to get sick of influenza A

Starting from working sick, going home together, sitting in his car normally. The next day, he was sick, but we were still normal to work. The evening of that day began to cough, but thought that it was normal because of the weather allergy. I thought that only the air conditioner in the office was cold. The third day went to work normally, but started to have a small fever. When the 3: 00 p.m., the fever started to take the antipyretic. When I put myself on the job until I stopped working, I got home to sleep because I couldn't. The fever grew up, the pain in my arm, the pain in my legs until my hands were numb. I fell asleep for a while until noon, because the fever rose to a height of 39. Take an antipyretic and sleep until morning. On the fourth day, wake up with a high fever, take another antipyretic because the girlfriend has to give up work to take him to the doctor because he can't go alone. When he reaches the hospital, he has to reduce the fever because he has the antipyretic, but the doctor checks if he has the flu or not. In a nutshell, he has to go home for five days to get better, but now he has two in three weeks and has not recovered.
