Sore Throat
Sore throat, also known as throat pain, is pain or irritation of the throat.
It is usually caused by pharyngitis (inflammation of the throat) or tonsillitis (inflammation of the
tonsils). It can also result from trauma.
About 7.5% of people have a sore throat in any three-month period.
Definition
Sore throat is a generic term used to describe the symptom of discomfort and pain in the throat
area. It does not specify the underlying cause.[2]
Signs and symptoms
The signs and symptoms of a sore throat vary depending on the underlying cause. However, the
common symptom shared by individuals with a sore throat is the feeling of throat pain and
discomfort, which is often worsened by swallowing or talking. Some people may complain of a
scratchy or dry sensation in their throat as well.
Because most cases of sore throat are caused by an infection, individuals may commonly
experience any of the additional following signs and symptoms:
Fever and/or chills
Nausea and/or vomiting
Body aches
Headache
Cough
Runny Nose or Nasal Congestion
Earache
Sneezing
Weakness
Lack of appetite
Redness and/or swelling of the tonsils and back of the throat
White patchy areas on the tonsils (exudate)
Swollen and/or tender lymph nodes in the neck
A muffled or hoarse voice
Differential diagnosis
A sore throat is usually from irritation or inflammation. The most common cause (80%)
is acute viral pharyngitis, a viral infection of the throat.[2] Other causes include other infections
(such as streptococcal pharyngitis), trauma, and tumors.[2] Gastroesophageal (acid) reflux
disease can cause stomach acid to back up into the throat and also cause the throat to become
sore.[3] In children streptococcal pharyngitis is the cause of 37% of sore throats.[4]
Management
Analgesics such as non-steroidal anti-inflammatory drugs (NSAIDs)
and paracetamol (acetaminophen) help in the management of pain.[5][6] The Mayo
Clinic advises gargling with salty warm water and resting the voice. Symptoms without active
treatment usually last two to seven days.[7]
Epidemiology
In the United States there are about 2.4 million emergency department visits with throat-related
complaints per year
