As coughs, colds and flu become more common during the colder months, it can sometimes be difficult to know whether you're dealing with a common seasonal illness or a chest infection.
Chest infections can develop after a cold or flu and share some of the same symptoms. However, there are certain signs people can look out for, according to a pharmacist.
Boots has shared advice on spotting a possible chest infection as the retailer launches a private Chest Infection Service in more than 90 stores across the UK.
Claire Nevinson, Superintendent Pharmacist at Boots, said symptoms of a chest infection can include a chesty cough producing coloured mucus, wheezing, shortness of breath and chest discomfort.
Other possible symptoms include a high temperature, headaches, aching muscles and tiredness.
She explained: "A chest infection is an infection of the lungs or large airways and they often follow a cold or flu, therefore symptoms can be similar.
"Symptoms of a chest infection may include a chesty cough with coloured mucus, wheezing and shortness of breath, chest discomfort, a high temperature, headaches, aching muscles and tiredness."
How long does a chest infection last?
According to the Boots pharmacist, symptoms will often get better without treatment within seven to 10 days, although a cough can remain for as long as three weeks.
People should seek medical advice from a GP if a cough lasts for longer than three weeks or they are coughing up blood.
What can you do for a chest infection?
There are several things people can do at home to help ease symptoms.
Nevinson recommends getting plenty of rest, drinking enough fluids and eating a healthy, balanced diet.
Sleeping with your head raised or using extra pillows may also make breathing easier.
Anyone whose symptoms persist, has had a cough for more than three weeks or is coughing up blood should seek medical attention from a GP, according to the pharmacist's advice.
Who is most at risk?
Some people are at greater risk of developing a serious chest infection.
Nevinson said this includes babies and young children, older people, pregnant women, people who smoke, those with long-term respiratory conditions such as asthma and people with weakened immune systems.
Boots launches new chest infection service
The advice comes as Boots launches a private Chest Infection Service for people aged 16 and over at more than 90 stores.
Appointments last 20 minutes and involve an assessment by an independent prescribing pharmacist, who can offer advice and discuss treatment options.
These could include over-the-counter medicines or, where considered appropriate, a course of antibiotics.
