Many chest infections aren't serious and get better within a few days or weeks. You won't usually need to see your GP, unless your symptoms suggest you have a more serious infection. While you recover at home, there are things you can do to improve your symptoms.
See a GP if you have a chest infection and:
you feel very unwell or your symptoms get worse. you cough up blood or blood-stained mucus. you've had a cough for more than 3 weeks.
Although most chest infections are mild and improve on their own, some cases can be very serious, even life-threatening. A bout of infection of the large airways (bronchi) in the lungs (acute bronchitis) usually gets better on its own within 7-10 days without any medicines.
Often viral cases of pneumonia begin as congestion and cough with or without fever in the first few days. When a doctor listens to the lungs and finds breathing sounds are not clear on either side of the chest, a viral cause over bacterial is even more highly suspected.
Antibiotics aren't recommended for many chest infections, because they only work if the infection is caused by bacteria, rather than a virus. Your GP will usually only prescribe antibiotics if they think you have pneumonia, or you're at risk of complications such as fluid building up around the lungs (pleurisy).
Chest infections are common, especially after a cold or flu during autumn and winter. Although most are mild and get better on their own, some can be serious or even life-threatening.
If your symptoms persist over more than seven days, you should make an appointment with your doctor. The doctor will make a physical examination to assess your condition. This may include listening to your breathing with a stethoscope, as wheezing can be a sign of pneumonia which requires more serious treatment.
Warning signs
"With a viral cough, you often have a fever which tends to go up and down," explains Coffey. "With a bacterial infection, such as pneumonia, you tend to have a consistently high fever - usually around 38-40°C." If your fever remains persistently high, it's worth giving your GP a call.
After 2 or 3 days, mucus may change to a white, yellow, or green color. This is normal and does not mean you need an antibiotic. Some symptoms, especially runny or stuffy nose and cough, can last for up to 10 to 14 days. Those symptoms should improve over time.
Your doctor will listen to your lungs with a stethoscope. If you have pneumonia, your lungs may make crackling, bubbling, and rumbling sounds when you inhale.
Will I get antibiotics? Both pharmacists can write prescriptions, so if after examining you they feel you have a bacterial infection they are able to write you a prescription for the most appropriate treatment. Many conditions are caused by viruses and do not require antibiotics.
See a GP if:
you've had a cough for more than 3 weeks (persistent cough) your cough is very bad or quickly gets worse – for example, you have a hacking cough or cannot stop coughing. you feel very unwell.
Most people will be contagious for up to 2 weeks. Symptoms are usually worse during the first 2 to 3 days, and this is when you're most likely to spread the virus.
A bronchitis cough sounds like a rattle with a wheezing or whistling sound. As your condition progresses, you will first have a dry cough that can then progress towards coughing up white mucus.
HOW LONG DOES A CHESTY COUGH LAST? Like most other coughs, a chesty cough will usually clear up on its own within a couple of weeks. If you've had a cold, it's usually the last symptom to go away. If your cough persists for longer than this or gets worse, please speak to a medical professional.
Is coughing up phlegm a good thing? Yes. While the presence of mucus may indicate an underlying issue, coughing up phlegm is a good thing because it helps clear irritants, allergens and infections out of your system.
If you have acute bronchitis, you might have cold symptoms, such as a mild headache or body aches. While these symptoms usually improve in about a week, you may have a nagging cough that lingers for several weeks.
The symptoms of a chest infection are more likely to include coughing and bringing up phlegm. An upper respiratory tract infection may cause a cough, but it can also produce symptoms such as sneezing, a blocked or runny nose and a sore throat. The effects of a chest infection will also tend to last a little longer.
A chest X-ray is often used to diagnose pneumonia. Blood tests, such as a complete blood count (CBC) see whether your immune system is fighting an infection. Pulse oximetry measures how much oxygen is in your blood. Pneumonia can keep your lungs from getting enough oxygen into your blood.
