Lingual papules, or small bumps on the tongue, can be caused by a variety of factors, and understanding their nature is crucial for determining the appropriate treatment. Based on your description of a semi-transparent white growth under your tongue that is not painful but causes a sensation of foreignness, it is possible that you are experiencing a condition known as "lingual varicosities," or it could be a benign growth such as a fibroma or a mucous cyst.

Causes of Lingual Papules:
1. Benign Growths: These can include fibromas, which are non-cancerous tumors made up of connective tissue. Mucous cysts, often caused by blocked salivary glands, can also appear as bumps under the tongue.

2. Lingual Varicosities: These are dilated veins that can occur with age and are typically harmless. They often appear as blue or purple bumps.

3. Irritation or Trauma: Sometimes, irritation from dental appliances, biting the tongue, or other forms of trauma can lead to localized swelling or bumps.

4. Infections: Viral infections, such as herpes simplex, can cause lesions on the tongue, though these are usually painful and may present with other symptoms.

5. Allergic Reactions: Allergies to certain foods or dental materials can cause localized swelling or bumps.

Treatment Options:
1. Observation: If the lingual papules are not causing pain or discomfort, they may not require immediate treatment. Many benign conditions resolve on their own.

2. Oral Hygiene: Maintaining good oral hygiene can help prevent irritation and secondary infections. Regular brushing and rinsing with salt water can be beneficial.

3. Avoiding Irritants: If you suspect that certain foods or dental appliances are causing irritation, try to avoid them.

4. Medical Evaluation: If the growth persists, changes in appearance, or begins to cause discomfort, it is advisable to seek medical evaluation. A healthcare provider can perform a thorough examination and may recommend a biopsy if there is any concern about the nature of the growth.

5. Surgical Removal: In cases where the growth is bothersome or if there is uncertainty about its nature, surgical removal may be considered.

When to Seek Medical Attention:
While many cases of lingual papules are benign, you should seek medical attention if:
- The growth changes in size, color, or shape.

- You experience pain, swelling, or other symptoms such as difficulty swallowing or speaking.

- There are signs of infection, such as increased redness, warmth, or discharge.

Given that you are currently overseas and considering returning to Taiwan for medical care, it is important to weigh the severity of your symptoms. If the growth is stable and not causing significant discomfort, you may choose to monitor it until you can see a healthcare provider. However, if you notice any changes or if your symptoms worsen, it would be prudent to seek medical attention sooner.

In summary, while lingual papules can be concerning, many are benign and can be managed with observation and good oral hygiene. However, a definitive diagnosis and treatment plan should be made in consultation with a healthcare professional.
