What Is a Blood Blister on Tongue

A blood blister on tongue is a small, red or purple bump filled with blood. It forms when tiny blood vessels under the skin break. This can happen because of irritation, injury, or other health problems.

Most of the time, a blood blister on tongue is harmless. It may feel uncomfortable, but it usually heals on its own. Understanding why it happens can help you take better care of your tongue and avoid future blisters.

How Does a Blood Blister on Tongue Look

A blood blister on tongue looks different from a normal blister. It is filled with dark red or purple blood instead of clear fluid. It can appear suddenly and may feel sore or tender.

These blisters usually form on the soft parts of the tongue. You may feel pain when eating, drinking, or talking. It is important not to pop the blister, as this can cause infection or slow healing.

Blood blisters on the tongue can appear for many reasons. Some causes are minor, while others may need medical attention.

• Biting the tongue: Accidentally biting your tongue can damage blood vessels and cause a blister.
• Eating hot or spicy foods: Hot drinks or spicy foods can burn the tongue and create blisters.
• Allergic reactions: Some foods or medications can cause irritation, leading to blisters.
• Medical conditions: Low platelet count or blood disorders may increase the risk of blisters.

Blood Blister vs. Other Mouth Sores: What’s the Difference?

Mouth sores can look similar, but they are not always the same. It is good to know the difference so you can treat them properly.

• Canker sores: These are small ulcers that are white or yellow, with a red border. They are painful but not filled with blood.
• Fever blisters: These are caused by a virus and usually appear on the lips or inside the mouth. They start with a tingling feeling before turning into blisters.
• Blood blisters: These appear suddenly and are filled with blood. They are not caused by infection or a virus.

When Should You Worry About a Blood Blister on Tongue

Most blood blisters are not dangerous, but sometimes they can be a sign of a bigger problem.

• If the blister does not heal in 10-14 days

Seeing a doctor can help you find out if there is an underlying health issue.
