Tongue Sensations: Causes and When to Seek Help - Otolaryngology

More Info

---

The sensation you are experiencing on the left side of your tongue, particularly the prickling feeling that intensifies when drinking water, can be attributed to several potential causes. Understanding these causes can help determine whether you should seek medical attention.

1. Nerve Irritation or Damage: The tongue is rich in nerve endings, and irritation or damage to these nerves can lead to abnormal sensations. This could be due to trauma, such as biting your tongue, or conditions affecting the nerves, such as glossopharyngeal neuralgia.

2. Infections: Viral infections, such as herpes simplex, can cause localized pain or discomfort in the mouth and tongue. Fungal infections like oral thrush can also lead to unusual sensations, although they typically present with other symptoms such as white patches on the tongue.

3. Allergic Reactions: Allergies to certain foods, medications, or dental products can cause localized swelling or irritation, leading to abnormal sensations in the tongue. If you have recently changed your diet or started new medications, this could be a factor.

4. Vitamin Deficiencies: Deficiencies in vitamins, particularly B vitamins (like B12) and folic acid, can lead to glossitis, which is inflammation of the tongue. This condition can manifest as swelling, pain, or altered sensations.

5. Burning Mouth Syndrome: This condition is characterized by a burning sensation in the mouth, including the tongue, without an obvious cause. It can be associated with anxiety, hormonal changes, or certain medications.

6. Oral Lesions: Conditions such as canker sores or leukoplakia can cause discomfort and abnormal sensations in the mouth. While you mentioned not seeing anything unusual, some lesions may not be immediately visible.

7. Psychological Factors: Anxiety and stress can manifest physically in various ways, including sensations in the mouth and tongue. If you are experiencing heightened anxiety, this could contribute to your symptoms.


When to Seek Help
You should consider seeking medical attention if:
- The sensation persists for more than a few days without improvement.

- You notice other symptoms, such as swelling, redness, or lesions on the tongue.

- You experience difficulty swallowing or speaking.

- The sensation is accompanied by pain, fever, or other systemic symptoms.

- You have a history of allergies or recent changes in medication or diet.


Conclusion
While occasional abnormal sensations in the tongue can be benign and self-limiting, persistent or concerning symptoms warrant a visit to a healthcare professional. A dentist or an ear, nose, and throat (ENT) specialist can perform a thorough examination, possibly including imaging or lab tests, to determine the underlying cause of your symptoms. Early intervention can help address any potential issues before they escalate.
