A viral infection

One of the most frequent causes of sore throat are viral infections such as the common cold and a nasty flu. In many cases these annoyances are caused by common viruses that do not require any antibiotic treatment; improvement simply happens after a few days.

Sore throat due to a viral infection happens because when a virus affects the upper respiratory tract, the body fights it by creating mucus to cleanse the body. Therefore, it is normal that our throat gets irritated after coughing so much to expel this mucus.

If you want to speed up the process of recovery, make sure you drink plenty of liquid and take acetylcysteine[1] (mucomyst) in order to get rid of the mucous.

Mononucleosis or the kissing disease is another common viral infection that can cause us sore throat. In this case, apart from a sore throat, you will also notice the following symptoms:

  • A high temperature
  • Lymph nodes swlooen
  • Headache
  • Rashes in areas of the skin
  • Fatigue

Gastric reflux

A sore throat can also be caused by more serious conditions such as gastric reflux. Gastroesophageal reflux occurs when stomach acid seeps into the esophagus, causing irritation in the throat after eating and that burning sensation of which we speak.

If you have a sore throat due to gastric reflux, you will also be able to notice the following symptoms:

If we have allergies it is also very possible that we suffer a burning sensation in the throat. Allergic reactions to dust mites, pollen, animals, food, etc., can lead an inflammation, among other symptoms. This kind of inflammation is what provokes the soreness and heat.

Bacterial infections

Other potential causes of throat soreness are bacterial infections such as:

  • Pharyngitis: A bacterial infection of the pharynx and causes burning and pain in the throat. It is accompanied by high fever, eye redness, pus plates and swollen glands. We'll have to treat it with antibiotic medication as prescribed by a medical specialist.
  • Tonsillitis: The tonsils become infected because of bacteria or a virus. Tolsillitis is characterized by swelling of the tonsils, which can become infected, with the visible appearance of pus. Among the symptoms of tonsillitis we should highlight difficulty swallowing, redness in the tonsils area, plaque, white tongue, fever, bad breath... Especially if your throat has become infected, it's important to visit your doctor so he or she can prescribe antibiotics.

Mild causes

Finally, there are also mild causes for a sore throat. Most of them are the result of specific activities or habits, and thus can easily be prevented. They include the following:

  • Eating hot food with which we can burn our throat slightly and feel burning, causing a lot of trouble.
  • Shouting too much or straining our voice can also cause soreness in the mouth and throat. For singers this is very common, and they have to take extra care in that area.
  • Smoking also causes a sore throat.
  • Mouth breathing during sleep can also irritate the throat.
