A sore throat on just one side when swallowing often stems from localized inflammation or irritation. Several factors could be responsible.
Possible Causes of Left-Sided Throat Pain When Swallowing
Here are some common reasons why you might experience throat pain specifically on the left side when swallowing:
-
Infections:
- Tonsillitis/Pharyngitis: An infection of the tonsils or pharynx (back of the throat) can cause localized pain. If the infection is more prominent on the left tonsil or side of the pharynx, the pain will be more pronounced on that side.
- Peritonsillar Abscess: A pocket of pus can form near one of your tonsils. This is a serious condition that can cause severe pain, difficulty swallowing, and fever, usually on one side. Seek immediate medical attention.
-
Canker Sore: A canker sore on the left side of your throat, tonsil, or the back of your mouth can cause sharp pain when swallowing.
-
Muscle Strain: While less common, it's possible to strain the muscles on one side of your throat, leading to pain when swallowing. This can happen from excessive coughing or yelling.
-
Referred Pain: Pain from another area, such as your ear or jaw, can sometimes be felt in your throat.
-
Tumor: Although rare, a tumor in the throat or surrounding structures could cause unilateral throat pain. This is more likely to be accompanied by other symptoms like persistent hoarseness, difficulty breathing, or a lump in the neck. This is a less likely but serious consideration and should be ruled out by a healthcare professional.
When to See a Doctor
It's important to consult a doctor if you experience any of the following:
- Difficulty breathing or swallowing
- Severe pain
- High fever
- A lump in your neck
- Hoarseness that lasts for more than two weeks
- Ear pain
- Symptoms that don't improve after a few days of home care.
A healthcare provider can properly diagnose the cause of your left-sided throat pain and recommend the appropriate treatment.
