My head hurts really bad and my whole body aches and my throat hurts...what can I do to feel better?

I'd say take a painkiller for the headache, get some good rest for the body aches (or maybe a nice warm bath may help a little, as well as massaging yourself where you hurt the most or having someone gently massage you...the painkiller for the headache may help these though) and gargle with salt water to help your throat feel a little better. If you're feeling hot though the warm bath might not be what you want. Be careful to monitor yourself for a fever in case you've gotten a flu of some kind. Hope you feel better and can get some rest soon! You and your body need it.
