Why Does My Tongue Hurt on the Side?

Common Causes of Tongue Pain

Pain on the side of the tongue can be attributed to several factors:

• Trauma or Injury: Biting the tongue, burning it with hot food or drinks, or irritation from dental appliances (like braces or dentures) can cause localized pain and discomfort.
• Infections: Viral infections, such as herpes simplex virus, can lead to painful sores on the tongue. Fungal infections, like oral thrush, can also cause discomfort and a burning sensation.
• Inflammation: Conditions such as glossitis (inflammation of the tongue) can cause swelling, redness, and pain. This can be due to various factors, including allergies, irritants, or nutritional deficiencies (such as vitamin B12 or iron deficiency).
• Nodular Swellings: Sometimes, nodular swellings on the tongue can occur due to various benign or malignant conditions. These can cause localized pain and should be evaluated by a healthcare provider.

Other Potential Causes

In addition to the common causes, other factors may contribute to pain on the side of the tongue:

• Allergic Reactions: Allergies to certain foods, medications, or oral hygiene products can lead to swelling and pain in the tongue.
• Systemic Conditions: Conditions such as autoimmune diseases (like lupus or Sjögren's syndrome) can affect the tongue and cause pain or discomfort.
• Neuropathic Pain: In some cases, nerve damage or irritation can lead to pain in the tongue, even without any visible lesions or injuries.

When to Seek Medical Attention

If you experience persistent or severe pain on the side of your tongue, especially if it is accompanied by other symptoms such as swelling, difficulty swallowing, or changes in taste, it is important to consult a healthcare provider. They can perform a thorough examination and determine the underlying cause of your symptoms.
