Hi, i'm 17 years old and I just had the strangest day.. I've had very light normal cold like a few days ago, just a stuffy nose and a very light cough.. Anyways I started to take theraflu?(its the one where you mix the powder in the drink and boil it) and it helped out a lot and I started to feel better within a couple of days..

Well today I woke up and I felt normal, I took a shower and went to walmart with my mom, but as I started walking around my body started feeling weak and a lil warm.. It's that same feeling you get when you have a fever, your bodies weak and it feels kinda buttery but I didn't have a fever just a slight chill.. When I came home I started having these headaches that I normally would have.. Around my temples, the side of my head.. And my head just feels are warm and tingly.. These headaches almost lasted all day and right now there starting to go away.. The whole day I felt very drowsy, I also slept almost all day with that same wierd feeling.. My hands and feet are really warm too...

Is this the flu or a cold? I just feel really bad right now and normally but colds never do this expecially give me a headache but if it was flu then why don't I have a fever?
