Tongue pain without visible lesions?


Hello Doctor: Thank you for taking the time to answer my questions.
I would like to ask about a recurring issue I have.
When my tongue brushes against my teeth, I often feel a swelling pain along the edges of my tongue, similar to the sensation of having bitten my tongue and the wound healing.
However, upon closer inspection, I do not see any visible wounds, redness, or whiteness in that area, yet I still experience that swelling pain.
This occurs quite frequently, about four to five times in six months, and it generally happens after I stay up late the night before.
Typically, the discomfort resolves within a day, and by the next day, I feel normal again.
My concern is heightened because my mother has Behçet's disease, which is characterized by recurrent mucosal ulcers.
I would like to know what other conditions could cause this swelling pain besides oral mucosal ulcers (since I really do not see any ulcer-like lesions).
Could it be related to staying up late? Is there any specific nutrition I should consider to prevent these occurrences? Thank you, Doctor.

Hello, Miss Anonymous: If there are no ulcers or wounds on the tongue but you still feel discomfort, it is possible that the mucosa of the tongue is in an inflammatory state.
This may be related to immune system dysregulation, emotional stress, irregular sleep, and lifestyle habits.
Additionally, dietary factors such as a deficiency in B vitamins may be involved.
It is recommended to consult a dentist or an oral surgeon for further examination.

More Info


Tongue pain without visible sores can be a perplexing issue, especially when it occurs frequently and seems to correlate with lifestyle factors such as lack of sleep. Your description of experiencing pain on the sides of your tongue, akin to the sensation of biting it, raises several possibilities that warrant consideration.

Firstly, one of the most common causes of tongue pain without visible lesions is oral mucosal irritation. This can occur due to various reasons, including friction from teeth, dental appliances, or even certain foods that may irritate the sensitive tissue of the tongue. Given that you mentioned the pain often follows a night of insufficient sleep, it’s possible that fatigue may exacerbate your sensitivity to these irritants.

Another potential cause is burning mouth syndrome (BMS), a condition characterized by a burning sensation in the mouth, including the tongue, without any identifiable cause. BMS can be associated with stress, hormonal changes, or nutritional deficiencies, particularly in vitamins such as B12, folate, and iron. Considering your family history of Behçet's disease, it’s understandable to be concerned about mucosal health. Behçet's can indeed cause recurrent oral ulcers, but it typically presents with visible lesions. However, it’s worth noting that some individuals may experience prodromal symptoms, such as pain or discomfort, before the appearance of ulcers.

Additionally, allergic reactions to certain foods, dental products, or medications can lead to localized swelling and pain in the tongue. If you’ve recently changed any products or introduced new foods into your diet, this could be a factor.

Nutritional deficiencies are another area to explore. A lack of essential nutrients can lead to various oral health issues, including glossitis (inflammation of the tongue), which may not always present with visible sores. Ensuring a balanced diet rich in vitamins and minerals is crucial for maintaining oral health. If you suspect a deficiency, consider consulting with a healthcare provider for appropriate testing and dietary recommendations.

Stress and anxiety can also manifest physically, leading to muscle tension and discomfort in the oral region. If you find that your symptoms worsen during stressful periods, it may be beneficial to explore stress management techniques such as mindfulness, meditation, or yoga.

In terms of immediate solutions, maintaining good oral hygiene is essential. This includes regular brushing and flossing, as well as using a gentle mouthwash. Staying hydrated and avoiding irritants such as spicy or acidic foods can also help alleviate symptoms. If the pain persists or worsens, it would be prudent to consult with a healthcare professional, such as a dentist or an oral specialist, who can conduct a thorough examination and possibly recommend further tests.

In conclusion, while the pain you are experiencing may not be indicative of a serious underlying condition, it is essential to monitor your symptoms closely. Keeping a diary of when the pain occurs, any associated activities, and dietary habits may provide valuable insights for your healthcare provider. If you have ongoing concerns, particularly given your family history, do not hesitate to seek professional advice for peace of mind and appropriate management.
