Why do I have Red bumps on the bottom of tongue?

Red bumps on the bottom of the tongue can be caused by a variety of conditions, including:

Canker sores: These are small, round, and typically white or yellow sores that can occur anywhere in the mouth, including the bottom of the tongue. Canker sores are usually harmless and heal on their own within a few weeks.

Herpangina: This is a viral infection that is characterized by small, red blisters on the back of the throat and tonsils. Herpangina can also cause sore throat, fever, and headaches.

Hand, foot, and mouth disease: This is a common viral infection that affects young children. It is characterized by a rash of red bumps on the hands, feet, and mouth. Hand, foot, and mouth disease can also cause fever, sore throat, and loss of appetite.

Oral thrush: This is a fungal infection that can occur in the mouth and throat. It is characterized by white or yellow patches that can be painful. Oral thrush is most common in infants and people with weakened immune systems.

Allergic reaction: Some people may develop red bumps on the bottom of the tongue as a reaction to certain foods, medications, or other substances. If you experience this symptom, it is important to identify the allergen and avoid it to prevent further reactions.

In some cases, red bumps on the bottom of the tongue may also be an indication of a more serious medical condition, such as:

Vitamin B12 deficiency

Iron deficiency anemia

Pernicious anemia

HIV

Sjögren's syndrome

If you experience red bumps on the bottom of your tongue that do not go away or seem to be worsening, it is important to see a doctor to determine the cause and receive appropriate treatment.
