What is Sore throat?

21:54 - 4 May , 2021


It appears through irritation, inflammation, dryness, and pain, aspects that worsen by swallowing. The most common origin of a sore throat or pharyngitis is the presence of a viral infection such as the flu, which heals in a few days without the need for treatment. 

There is another less common type of sore throat that is caused by a bacterial infection, which must be treated with antibiotics to avoid major problems.

How to prevent it:

Diagnosis and treatment Sore throat

Once your doctor analyzes your symptoms and medical history, he or she will perform a physical examination that includes: 

  • Observing the throat, ears, and nose.
  • Feeling your neck and jaw for swollen lymph nodes.
  • Listening to your breathing with a stethoscope.

Also, he or she can perform a throat swab to send the secretion sample to be analyzed in the laboratory and determine the type of bacteria that is causing the infection. 

When the origin of the sore throat is a viral infection, treatment is not required and usually lasts a week, where painkillers can be taken to relieve symptoms. It usually lasts five to seven days and does not require medical treatment. 

In the case of bacterial infections, the prescription of antibiotics is necessary for a certain period, a period that must be met even if the symptoms have disappeared, otherwise there is a risk of worsening or becoming resistant to the bacteria in question.
