The symptoms of influenza, or ‘flu, include a sudden fever, a dry and chesty cough, headache, tiredness, chills, aching muscles, limb and joint pain, upset stomach, sore throat, runny nose, sneezing and sleep disturbance.
In general, symptoms are at their worst after two to three days and if all goes to plan, you should be well after a week or so. However, many people experience a chesty cough that continues, loss of energy and severe tiredness for several weeks.
As ‘flu shares symptoms with bacterial chest infections and other conditions, it’s worth seeing a doctor for a clear diagnosis and medical support. If you have asthma, diabetes, heart disease, weakened immunity or other conditions exacerbated by a viral or bacterial infection, it is vital to see a GP.
