Fevers usually go along WITH the flu.
And it certainly sounds like a flu bug to me... not a cold, because colds usually don't hit you that badly!
If your fever has hit or gone over 101*C, then get yourself a doctor. Otherwise: Rhap gave a good suggestion. Take the pills your doc said, drink lots of fluids, try to eat soup and lots of sleep. Vitamin C (orange juice) and echinacea(sp) probably would also help.
If you've got the chills and "hot flashes" that usually means you've got a fever. Check your temperature out with a thermometer, definitely a good idea.
I'm not a doctor, but I know my general "flu bug" routine and recuperation.
