Sore Throat

Sore throat is a viral infection that causes severe pain, irritation, and stretchiness in the throat. The throat becomes swollen, and a person feels difficulty in normal breathing and swallowing food caused by bacteria, cold, and flu. Mostly, it can cure on its own over time, though simple home remedies also give comfort to this problem. While it requires proper check-ups and medication in severe cases.


Sore throat is categorized into the following types based on its symptoms:

  • Pharyngitis: It affects the back area of the mouth. The pharynx becomes inflamed and creates difficulty in swallowing the food.
  • Tonsillitis: The soft tissues in the back of the throat called tonsils become red and swell.
  • Laryngitis: The larynx is a voice box in the back of the throat that becomes red and swallowed. A person feels irritated by it, and the voice may disappear for a short time.

Strep throat: It is a viral infection that makes your throat scratchy, swallow, tender, and extremely painful caused by the bacteria  ‘Streptococcus Pyogenes’.


There are many causes, Some of them are listed below:

  • Bacterial and viral infections: About 90 percent of sore throat is caused by viruses and bacteria. Common cold, influenza, chickenpox, measles, mononucleosis, and COVID-19 are the common viral infections that sore the throat. Among the bacterial infections, the most communal cause is Streptococcus pyogenes (group A streptococcus). This infection swells the tonsils and causes severe pain in the neck area.
  • Allergies: Allergy is triggered by dust, pollen grains, pet dander, and molds that can lead to continuous sneezing, producing water in the eyes. This condition congested the nasal. Due to these allergies, extra mucus builds in the throat, irritating and creating inflammation. This condition is called postnasal drip. This problem may get worse with time if not treated in time.
  • Dryness: In winters, the air becomes dry, making the throat rough and scratchy. Due to the lack of moisture, the throat becomes sore. Nasal congestion is also the leading cause of dryness in the throat.
  • Air pollutants: Harmful chemicals and irritants like cigarette and tobacco smoke, emitting harmful gases from factories, and cleaning products can cause chronic infection in the throat. Moreover, eating spicy food and drinking litmus juices can become reasons for soreness in the throat.
  • Gastroesophageal reflux disease (GERD):  It is a digestive system disorder in which the stomach backs up its gastric juice and acid in the esophagus. This acid or juice burns up the esophagus and leaves a sore throat. Common symptoms of this disease are heartburn and the regurgitation of stomach juice into the throat.
  • Tumors: The cancer of the throat and larynx is also a cause of sore throat. Common signs of having a tumor in the throat are neck pain, swelling, blood in saliva, or a lump in the throat.
  • Injuries: Any neck injury like a cut on the neck or hitting by something hard can cause sore throat. Vocal cords become swell by continuous loud talking, singing, and yelling.

  • Allergy: Seasonal and environmental allergies increase the risk of having a sore throat.
  • Irritants: Indoor and outdoor chemicals, smoke, and irritants also increase the risk of developing a sore throat.
  • Congested areas: People living in closed and congested areas are more likely to develop a sore throat. The fresh air cannot pass through these areas, and they have to breathe in the same polluted air, which increases their risk factor.
