What is sore throat?

Sore throat, also called pharyngitis, is a condition marked by pain in the throat, typically caused by inflammation due to a cold or other virus. It also refers to a discomfort, pain, scratchiness or irritation in the throat.

You may have difficulty swallowing food and liquids, and the pain may get worse when you try to swallow. Throat pain is the primary symptom of a sore throat. Other symptoms due to cold that may accompany the sore throat includes:

  • Dry throat
  • Fever
  • Runny nose
  • Cough
  • Headache
  • Hoarse voice
  • Joint pain / muscle aches
  • Swollen glands in the neck
  • White patches on the tonsils

CAUSES OF Sore Throat

Sore throat has many different causes and proper treatment depends on understanding the cause of a sore throat.

Viral infection

Most sore throats are triggered by a viral infection which is usually caused by the flu virus.

Bacterial infection

A bacterial infection can also cause a sore throat and this includes strep throat, diphtheria and whooping cough.


Some people may be allergic to pet dander, molds, dust and pollen. Exposure to these allergens can trigger post-nasal drip where excess mucus accumulates in the back of your throat. This accumulation can irritate your throat and cause pain or inflammation.


Dry air can make your throat feel raw and scratchy, particularly in the morning when you first wake up. Breathing through your mouth, often because of nasal congestion, can also cause a dry and sore throat.


Outdoor air pollution and indoor pollution like tobacco smoke or chemicals can also cause persistent sore throats.

Muscle strain

Throat strain from yelling or too much talking can result in a sore throat and hoarseness.

Gastroesophageal reflux disease

GERD is a digestive system disorder characterized by the back flow of stomach acids or other contents into the esophagus. This can cause symptoms such as sore throat, hoarseness, heartburn, and nausea.


Alcoholic beverages and spicy foods may also irritate your throat.

Treatment for
sore throat

Most sore throats heal without complications, but they should not be ignored. If the cause of your sore throat is a virus, your doctor will likely recommend that you drink plenty of fluids, get plenty of rest, and take an over-the-counter pain reliever if needed.

Antibiotics will not help and will not shorten the duration of a sore throat caused by a virus.

Antibiotics are prescribed if the sore throat is caused by bacteria, such as Streptococcus. If antibiotics are prescribed, it is important to take the entire course of medication exactly as prescribed. Stopping before your medication is finished because symptoms have cleared up can encourage antibiotic resistance—always take the full course.

The following tips may also help your sore throat feel better:
  • Get enough rest and avoid straining your throat
  • Drink plenty of fluids to keep yourself hydrated
  • Drink cold liquids or suck on popsicles to help relieve soreness
  • Avoid alcohol and caffeine which can cause dehydration
  • Avoid allergens and irritants such as smoke and chemicals
  • Use a cool-mist vaporizer or humidifier to help moisten the air and soothe a dry throat
  • Ask your doctor or pharmacist about local preparations, presented mainly as lozenges, gargles or buccal sprays, containing anti-inflammatory drugs (e.g. benzydamine), anesthetics, and antiseptics
Note: It is advisable to see a doctor if a sore throat persists for more than a few days or is accompanied by fever, nausea or abdominal pain.
