Doctors or nurses - what type of virus do I have?

I woke up 2 days ago with a terrible headache, sore throat, and very congested. I was supposed to go to Cross Country that morning, but I stayed home and rested. I felt better later so I went running on my own. Yesterday, my virus got worse. I felt extremely tired, somewhat dizzy upon standing, and my stomach hurt after I ate, along with the other systems. I developed a alight cough as well. Today, when I woke up I am still sick, and i noticed both of my eyelids are drooping. The right one drooped only a little bit, but the left one ia halfway down. I've been taking Nyquil/Dayquil and resting, drinking fluids, etc. I keep getting hot sweats, but I have no fever, What could be the cause of my virus, I can I treat it, and should I go to the doctor?
