Cold-like symptoms (such as a dry or chesty cough, blocked or runny nose, sneezing and a sore throat) can also be caused by flu, but they tend to be less severe than the other flu symptoms you may have.1

You can keep feeling tired for weeks after catching flu and may have to stay in bed and rest until you feel better.1

Talk to your GP, nurse or pharmacist if you would like further information or advice about flu and flu symptoms.
