Tongue Issues: Causes of Red Bumps Under the Tongue - Otolaryngology

When it comes to the appearance of red bumps or lesions under the tongue, there are several potential causes to consider. The fact that you are experiencing a small, red bump that is not painful but gives a sensation of an abnormality is not uncommon. These types of lesions can arise from various factors, including irritation, inflammation, or even minor infections.

One common cause of red bumps under the tongue is irritation from certain foods. You mentioned that you have been eating oily or greasy foods recently. High-fat foods can sometimes lead to irritation of the oral mucosa, especially if they are spicy or acidic. This irritation can manifest as redness or small bumps. Additionally, if you have recently changed your diet or introduced new foods, this could also be a contributing factor.

Another possibility is that the bump could be related to a condition known as "lingual varicosities," which are enlarged veins that can appear under the tongue, often as a result of aging or increased pressure in the veins. These are typically harmless and do not require treatment unless they cause discomfort.

In some cases, the bump could be a minor form of oral thrush, which is a fungal infection that can cause white or red lesions in the mouth. However, this is usually accompanied by other symptoms, such as a burning sensation or difficulty swallowing, which you have not mentioned.

Another potential cause could be a mucocele, which is a cyst that forms when a salivary gland becomes blocked or damaged. Mucoceles can appear as painless bumps and are often clear or bluish in color, but they can also appear red if there is irritation or inflammation.

If the bump persists for more than a week or two, or if you notice any changes such as increased size, pain, or other symptoms like difficulty swallowing or changes in taste, it would be advisable to consult a healthcare professional. An examination by a dentist or an ear, nose, and throat (ENT) specialist can provide a more accurate diagnosis. They may perform a physical examination and, if necessary, additional tests to rule out any serious conditions.

In the meantime, maintaining good oral hygiene is essential. Rinse your mouth with warm salt water to help reduce inflammation and promote healing. Avoiding spicy, acidic, or irritating foods can also help alleviate any discomfort.

In summary, while the red bump under your tongue may be due to irritation from dietary choices or other benign causes, it is important to monitor the situation. If it does not resolve or worsens, seeking medical advice is the best course of action to ensure proper diagnosis and treatment.
