People get sore throats often. Coughing, sneezing, or fever often accompany moderate to severe discomfort. Sore throats are minor, but they can impair daily life. Knowing sore throat on one side causes symptoms, and remedies can reduce discomfort and speed recovery. Tonsillitis, mononucleosis, and throat cancer are rare causes of prolonged throat pain. A throat infection may not be dangerous, but don’t ignore any alarming signals and visit a doctor to treat the cause and avoid the consequences. 

Sore throats, or pharyngitis, can be annoying, especially when they affect only one side. Sore throats usually occur from viral infections like a common cold or flu, but pain, itchiness, or scratchiness on one side may call into question other reasons. Both sides of the throat are affected by sore throats, which can be painful. However, one-sided sore throats can be associated with other symptoms.

Causes of Sore Throat

Following are the causes of one side throat:

Nasal Drainage 

Mucus drips from the back of your nose. It may feel like mucus in your throat. Your nose and throat glands create 1-2 liters of mucus daily. Infections and allergies cause greater mucus production. Flowing mucus down your neck can be painful when it builds up and doesn’t drain. 

A sore throat is often caused by postnasal drip. You may have severe aches on only one side, particularly in the early hours after resting on your side. Postnasal drip is treated by addressing the underlying problem. You can relieve symptoms with pseudoephedrine until then. 


Usually caused by infection, tonsillitis involves inflammation. The back of the throat, which is behind the tip of your tongue, has two circular lymphatic tissue balls called tonsils. A sore throat on one side can result from tonsillitis. 

 Most sinusitis is caused by viruses, although bacteria can also cause it. A sore throat is the main symptom, often accompanied by: 

  • Fever and unpleasant breath 
  • Nasal congestion and runny nose 
  • Lymph node swelling 
  • Red, swollen tonsils with pus patches Difficulty swallowing Headache 
  • Pain in the lower abdomen and bleeding tonsils. 

Most viral tonsillitis heals in 3–4 days. OTC painkillers or saltwater gargling can relieve the pain. 

Peritonsillar Abscess 

A pus-filled peritonsillar abscess forms next to and behind one of your tonsils. It frequently follows bacterial tonsillitis and is more common. Despite broad throat pain, peritonsillar abscesses usually hurt more on the afflicted tonsil. 

Other peritonsillar abscess symptoms: 

  • Difficulty opening the mouth, fever, and weariness. 
  • Problems with speech include earache, foul breath, drooling, and a muffled voice. 
  • A peritonsillar infection needs rapid treatment. Your doctor may drain pus with a needle or small incision. After draining the abscess, you may receive antibiotics. 

Swollen Lymph Nodes 

Lymph nodes combat infections. Swelling usually indicates an infection caused by a bacteria or virus. Local lymph nodes enlarge during infections. Strep throat can enlarged neck lymph nodes. When one lymph node swells, one side of the throat hurts. Swollen lymph nodes could indicate cancer or HIV in uncommon situations. Swollen lymph nodes may cause these symptoms; therefore, consult a pain management in Dallas. Swollen nodes lasting over 2 weeks of weight loss 

A Night’s Sweat 

Chronic fever, weariness, hard or growing nodes, swollen nodes near the collarbone or neck, red or irritated skin, and difficulty breathing are symptoms of this condition. 


Laryngitis is larynx inflammation. Overusing your voice, annoyance, or a virus generally causes it. The two laryngeal voice cords open and close smoothly to generate sound. Swollen or inflamed chords can cause pain and vocal changes. One chord may be more inflamed, causing throat pain on one side. 

Other laryngitis symptoms:  

  • Sound of Hoarseness 
  • Loss of Voice 

Hand-Foot-Mouth Disease 

The Coxsackie virus causes diseases such as the hand, foot, and mouth. It’s more prevalent in young people under 10 but may impact adults as well. Through personal touch or droplets from coughing, sneezing, or talking, the virus spreads. It can also be spread by infected doorknobs or toys. Fever and sore throat usually emerge three to five days after virus contact in hand, foot, and mouth disease.  

Tongue and mouth sores can blister and make swallowing, eating, and drinking difficult. One side may feel this more, depending on where the sores form. Blisters can form on hands and feet. The treatment for hand, foot, and mouth disease remains unknown. Most instances resolve within 7–10 days (about 1 and a half weeks). Infected people should stay hydrated and take over-the-counter pain and fever treatments.
