The symptoms of flu* include:
- Sore throat
- Muscle aches
*Influenza, not gastric or 'stomach' flu.
If you feel a fever come on all of a sudden and are really struggling with more severe cold-like symptoms but have aches and pains too – perhaps even to the point that you can barely get out of bed – it is more likely to be the flu, and not a cold.
Why the fever?
One of the main symptoms that differentiates the flu from a common cold is the high fever. As unpleasant as a fever may be, the rise in temperature - caused by chemicals called pyrogens - is your body's way of attempting to kill infective agents that have entered your system.
