Thank you for sharing your concern about the black spot on your tongue. While most tongue discolorations are harmless, a persistent black spot lasting two weeks warrants proper evaluation to rule out underlying causes.
Possible Causes of Black Spot on Tongue
1. Benign Conditions:
- Hairy tongue: Accumulation of keratin causing dark patches
- Pigmentation: Normal melanin deposits (common in darker skin tones)
- Trauma: Biting or burning the tongue
2. Nutritional Factors:
- Iron/
B12/folate deficiency (can cause tongue discoloration)
- Smoking or certain medications
3. Less Common But Important:
- Oral melanotic macule (harmless but should be diagnosed)
- Rarely, early signs of oral melanoma (very uncommon in your age group)
Recommended Next Steps:
1. Self-Examination:
- Check if the spot is raised/flat
- Note any changes in size/texture
- Monitor for pain/bleeding
2. Professional Evaluation Needed For:
- Any growing/changing lesion
- Spots that bleed easily
- Associated symptoms like pain or swelling
3. Diagnostic Options:
- Oral examination with torch light
- Possibly a biopsy if suspicious features exist
Since this spot has persisted for two weeks despite normal blood tests, I recommend an in-person consultation for proper visualization and diagnosis. Many tongue discolorations are harmless, but professional assessment is crucial for accurate diagnosis and peace of mind.
