Tongue pain

Disease Description (Causes and Symptoms)

• Disease name: Glossodynia (may overlap with the symptom group of burning mouth / tongue pain)
• Causes and pathophysiology: Pain and a burning sensation that occur when there is no clearly identifiable structural abnormality of the tongue or oral cavity. Factors involved may include local irritation (teeth, prostheses, or oral mucosal irritation), dry mouth (reduced saliva secretion), smoking, hormonal changes (such as menopause), nutritional deficiencies (such as B vitamins and iron), metabolic diseases (diabetes and thyroid abnormalities), medication side effects, psychosocial factors (stress, anxiety, and depression), and, rarely, neuropathic mechanisms such as trigeminal neuropathy. Symptoms may also worsen because of anxiety about cancer, so it is important to rule out malignant lesions.
• Main symptoms: Tingling or prickling sensations at the tip or edges of the tongue, a burning sensation, and taste disturbances (changes in taste or reduced taste sensitivity); symptoms may spread throughout the oral cavity. In general, no notable lesion is often observed on visual examination or palpation.

Treatment Methods

• General principles: Identify and correct or treat possible causes (local irritation, medications, nutritional deficiencies, systemic diseases, etc.). If symptoms persist even after the cause has been eliminated, symptomatic treatment for relief and psychosocial approaches are used together.
• Medication treatment
  • Antidepressants (tricyclic antidepressants, some SSRIs/SNRIs; some antidepressants may help relieve pain) or anxiolytics (when necessary) — used when psychosocial factors are significant.
  • Local treatment: Steroid gargles (short-term), antifungal agents (when Candida infection is suspected), and topical preparations or ointments containing local anesthetics (such as products containing propolis or hyaluronic acid) may help relieve symptoms.
  • Medications for controlling neuropathic pain (such as gabapentin and pregabalin) may be considered when the symptoms have a strong neuropathic character.
• Nonmedication treatment
  • Behavioral therapy (such as cognitive behavioral therapy), stress management, and relaxation therapy.
  • Oral moisturizers, adequate fluid intake, smoking cessation, and improved oral hygiene.
• Procedures/surgery: Usually not necessary. If a local lesion (for example, a lesion suspected of being malignant) is found, a biopsy and the relevant treatment are performed.
• Follow-up and specialist referral: If symptoms persist or worsen, evaluation and treatment should be coordinated with oral and maxillofacial surgery, otolaryngology, dentistry, neurology, or psychiatry.
• Precautions/risks of complications
  • An examination to rule out cancer at an early stage (checking for lesions in the oral cavity and performing a biopsy if necessary) is important.
  • If left untreated for a long time, anxiety and depression may develop, as well as nutritional problems caused by reduced food intake.
  • Self-treatment (such as excessive use of mouthwash or irritating substances) may worsen symptoms.

Checklist Before an Outpatient Visit (Including Example Questions)

• Items to prepare
  • A list of all medications currently being taken (including prescription drugs, OTC medications, herbal medicines, and supplements)
  • Past medical history (especially diabetes, thyroid disease, psychiatric care, and a history of cancer) and surgical history
  • Recent blood test, imaging test, and oral examination results (if available)
  • Symptom diary: when symptoms began, location (tip/edge of the tongue, front of the tongue, or entire oral cavity), factors that worsen or relieve symptoms, relationship to meals and stress, and whether there have been changes in taste
  • Lifestyle information: smoking and alcohol use, symptoms of dry mouth, and the condition of dental prostheses
• Show the doctor during the visit
  • Photos (photos inside the mouth of the affected area) or symptom records (pain intensity and time of day)
• Example questions (to consider before the visit)
  • Are the symptoms worse at a particular time of day?
  • Have there been any recent medication changes or hormonal changes (for example, menopause)?
  • Is dryness in the mouth or a change in the surface of the tongue (such as redness or a white coating) also present?

General Example Questions to Ask the Doctor

• "What are the possible causes of this pain? What additional tests should I have?"
• "What are the expected effects and side effects of the medication you plan to prescribe?"
• "If my symptoms do not improve, what are the next treatment options (such as other medications or psychotherapy)?"
• "How likely is it that this condition is related to cancer? Is a biopsy necessary?"

Examples of Condition-Specific Questions

• "There was no clearly identifiable lesion on the examination of my mouth, but the pain persists. What tests should I undergo to definitively rule out cancer?"
• "I am under a lot of stress and also have depressive symptoms. Which would you recommend prioritizing, medication treatment (antidepressants) or behavioral therapy, or is a combination necessary?"
