Sore throats are a common ailment, responsible for about 10% of primary healthcare visits each year. Many sore throats are caused by bacterial or viral infections and can be treated at home.
There are also instances where the pain is localized to just one side. Identifying the cause of a one-sided sore throat is helpful when it comes to embarking on a course of treatment.
Potential Causes
There are a few potential causes of a sore throat localized to one side of the throat, each with its own treatment and symptom management options. Conditions may include:
- Tonsillitis: Tonsillitis involves inflammation or infection of the tonsils and can affect one or both sides of the throat. Treatments include over-the-counter pain relievers from places like Lecare Pharmacy, or antibiotics. In recurrent cases, a tonsillectomy, or surgery to remove the tonsils, may be necessary.
- Postnasal drip: Mucus trapped on one side of the throat due to postnasal drip can cause soreness and inflammation. If you experience swelling or pain, contact your doctor.
- Canker sores: Canker sores can result from various factors including injury, allergies, stress, irritants or disorders, and may appear on one side of the throat. These sores can also develop in the mouth, lips and cheeks.
- Swollen lymph nodes: Infections that challenge the immune system can lead to swollen and painful lymph nodes. Antibiotics may be needed, and persistent swelling should be evaluated by a doctor to rule out conditions like lymphoma or other cancers.
- Dental issues: Dental issues, such as a tooth abscess or infection, can lead to one-sided throat swelling. If this is accompanied by tooth pain, see your dentist.
- GERD: Digestive issues or indigestion, along with a sore throat, might indicate acid reflux. Consulting a doctor can help determine the best treatment options.
- Laryngitis: Laryngitis, an infection of the voice box, can be triggered by allergies, overuse of the voice, smoking or other infections. Most cases are resolved within a week.
- Peritonsillar abscess: A peritonsillar abscess, a complication from tonsillitis, can cause swelling on one side of the throat due to an infected tonsil.
Though uncommon, persistent, one-sided throat pain could be a sign of head or neck cancers, so if a sore throat persists for more than one week without improvement, whether on one-side or the entire throat, consult a doctor. An ENT can help provide effective diagnosis and proper treatment or symptom management.
