Getting a sore throat on one side can be a problem. If you are having a problem with your throat, then there are several things that you should do. 

You need to know what the symptoms of a sore throat on one side are so that you can treat the problem effectively.

Understanding a Sore Throat on One Side


Symptoms of laryngitis include a hoarse voice, loss of voice volume, and a decreased ability to speak. These symptoms are not serious and usually go away on their own within a few weeks. 

However, if you are experiencing persistent throat pain or are unable to talk or swallow normally, you should contact your doctor immediately.

Laryngitis is caused by viruses, bacteria, or other factors. Viral infections include rhinovirus, influenza, and Coronavirus. Symptoms of a viral infection usually improve within a few days. However, your voice may remain croaky after the virus has passed.

In some cases, a sore throat on one side can be a symptom of cancer. The Healthline website writes that in rare cases, swollen lymph nodes can be a sign of cancer or HIV. 

The pain is typically vague, and will vary depending on the tumor’s location. Symptoms are more obvious in the advanced stages.

Postnasal drip

Having a sore throat on one side can be a serious problem. When it occurs, you should consult your doctor to determine the cause of the condition and how to treat it. 

If you have a sinus infection, your doctor may prescribe antibiotics to clear the infection. If you have allergies, you can also get allergy tests, which will help your doctor determine what causes your symptoms.

Postnasal drip can be caused by a number of conditions, including allergies and asthma. Some people are at greater risk of developing postnasal drip than others. A few other factors, such as cold temperatures, a deviated septum, or nasal polyps, can also cause the condition.

symptom of postnasal drip is the presence of thick mucus in the back of the throat. This mucus is produced by the mucus glands in the nasal passages. These glands produce a couple of quarts of mucus daily. 

However, when you are sick or have allergies, the glands produce more. This means that the extra mucus may not drain properly and can cause postnasal drip.


Having a sore throat on one side can be a sign of tonsillitis or another infection. You should see your doctor if the sore throat is persistent. If it does not improve, you may need to have your tonsils removed.

Tonsillitis occurs when the tonsils become inflamed. This can be caused by viruses or bacteria. The treatment is usually antibiotics. A doctor will also test your blood for infection.

Tonsillitis is usually not contagious. However, if you have it in your family, you should keep your kids away from people who have it. It is important to keep your mouth clean and drink plenty of water. Also, avoid sharing food, towels, and napkins.

Tonsillitis may be caused by infection of the lymph nodes. The lymph nodes are the swollen and tender areas of the neck and jaw. If your child is experiencing tonsillitis, your child should be given antibiotics.

Peritonsillar Abscess

Having a sore throat on one side can be a sign of a peritonsillar abscess. This infection is caused by streptococcal bacteria. In the early stages, it is treated with antibiotics. But if it becomes more serious, you might need to undergo surgery.

This infection can also lead to pneumonia. Symptoms include fever, difficulty swallowing, and pain. You might need to visit the emergency room if you have trouble breathing. Your doctor will do a physical exam and take a throat culture to confirm the diagnosis.

If the doctor finds an abscess, he will use a needle or a lance to drain the pus. You may also receive antibiotics, painkillers, and intravenous fluids. If the abscess is too large, your doctor may also need to take out your tonsils.


Getting a sore throat on one side is often caused by epiglottitis. The NHS states that epiglottitis is often caused by infection, but can also be caused by injuries to the throat.

This inflammation can make breathing difficult or even cause a person to collapse. Epiglottitis is a medical emergency and needs immediate treatment.

Infections that can cause epiglottitis include otitis media, shingles, meningitis, and bacterial pneumonia. These infections can be spread from the epiglottis to other parts of the body.

Some of the early symptoms of epiglottitis include: 

  1. Fever
  2. Irritatability
  3. Difficulty swallowing

A person may also experience changes in skin color. These symptoms may be accompanied by a high-pitched whistling sound. 

If these symptoms appear, an ambulance should be called. The medical team will monitor the person’s breathing and administer fluids through an IV drip.

In some cases, the infection is so severe that a tracheostomy or airway intervention equipment may be needed. A tracheostomy is a surgical procedure that involves cutting the front of the windpipe to allow air to pass through. This procedure is necessary to prevent respiratory failure.
