When experiencing painful swelling under the tongue, particularly if you notice a tubular structure resembling a blood vessel that has become prominent or is hanging down, it is important to consider several factors before determining whether medical attention is necessary.

Firstly, the area under the tongue is rich in blood vessels and salivary glands, making it a sensitive region. The structure you describe could potentially be a dilated blood vessel, a swollen salivary gland duct, or even a mucous cyst (also known as a ranula). If this structure is painful, it may indicate inflammation or irritation, which could be due to various causes such as trauma, infection, or blockage of a salivary gland.

Here are some key points to consider regarding your symptoms:
1. Duration and Progression: If the swelling and pain have persisted for more than a couple of days or are worsening, it is advisable to seek medical attention. Persistent symptoms could indicate an underlying issue that requires treatment.

2. Associated Symptoms: Pay attention to any additional symptoms such as fever, difficulty swallowing, or changes in taste. The presence of these symptoms could suggest an infection or more serious condition that warrants immediate medical evaluation.

3. Trauma or Irritation: If you have recently experienced trauma to the area (such as biting your tongue or irritation from dental appliances), this could explain the swelling and pain. In such cases, monitoring the situation for a few days may be appropriate, but if symptoms do not improve, a visit to a healthcare provider is recommended.

4. Infection Risk: If you notice signs of infection, such as increased redness, warmth, or pus, it is crucial to seek medical care. Infections in the oral cavity can spread quickly and may require antibiotics or other interventions.

5. Underlying Conditions: If you have a history of oral health issues, such as frequent canker sores or salivary gland problems, it may be beneficial to consult with a healthcare provider to rule out any chronic conditions.

In summary, while some minor swelling or irritation under the tongue may resolve on its own, the presence of pain, especially if associated with a noticeable change in the anatomy of the area, should not be ignored. It is always better to err on the side of caution when it comes to changes in your health. If you are in doubt, or if the symptoms persist or worsen, it is advisable to seek evaluation from a healthcare professional, such as a dentist or an ear, nose, and throat (ENT) specialist. They can provide a thorough examination, determine the cause of your symptoms, and recommend appropriate treatment options.
