A sore throat (or pharyngitis) is a very common condition usually caused by an infection in the throat. Usually this will be a viral infection, and will settle in a few days with medications targeted at helping ease your symptoms.
Sometimes a bacterial infection, or an infection such as bacterial tonsillitis or glandular fever can cause it. Some people also suffer from a chronic sore throat caused by irritants such as smoking, pollution or allergies, or from other conditions such as acid reflux.
This blog will primarily deal with an acute (short term) sore throat caused by an infection.
Aside from the throat being sore, you may also experience:
Many people have a sore throat as a part of a cold or the flu. This tends to be relatively milder in severity (although of course, still very frustrating).
Viral infections can affect any part of your mouth and throat, from the tonsils, the pharynx (throat, causing pharyngitis) or the larynx (or voice box, causing laryngitis).
Tonsillitis is an infection of the tonsils at the back of the throat. This can be caused by a virus or bacteria, and in tonsillitis you may find your symptoms are much worse with a higher fever and feeling more unwell than with a usual sore throat associated with a cold. You may be able to see your tonsils are enlarged or that there is pus on them.
Some patients with severe tonsilitis or those who develop complications (such as a tonsil abscess or ‘quinsy’) may need to go to hospital for intravenous antibiotics, fluids and other supportive treatment, although this is not common. Other infections, such as glandular fever (infectious mononucleosis or “mono”).
Not usually. Your doctor can usually help to predict what is causing your sore throat based on an assessment of your symptoms and an examination of your throat.
Sometimes a swab will be done from the throat to analyse the germs depending on your situation.
You may need a blood test if you are suspected to have a condition called glandular fever or if you are on certain medications or have certain medical conditions that put you at risk of a low white blood cell count.
Usually you will not need an antibiotic. It is important not to give antibiotics when they are not required as firstly, they can cause unwanted side effects, and secondly, there is a risk of the antibiotics becoming less effective over time as the more the bugs are exposed to the antibiotic, the better they get at adapting and “beating” them.
As mentioned above, most sore throats are caused by viruses, and antibiotics are only helpful if your infection is bacterial. Sometimes your body will actually be able to deal with bacterial throat infections really well on its own too. However there are certain indicators that can suggest antibiotics might be needed (see below)
If you fit 3 or 4 of the below symptoms, it is worth coming in for an assessment with your doctor as it is possible that you will require antibiotics (although not always).
Most cases of sore throat will settle within a few days with rest, hydration and medication to relieve your symptoms:
A sore throat will typically get worse over two to three days and then start to improve. Most people will be feeling better in a week’s time with supportive treatment.
You should see a doctor if any of the following apply to you
The 'take home' message is to see a doctor if symptoms of a sore throat are very severe, unusual, or you are still feeling worse or no better in 3-4 days.
