Bumps on Back of Tongue

A normal tongue possesses several natural bumpy projections. Compared to the other parts of the tongue, the bumps on the back of the tongue are larger in size. Some of these large projections on the surface of the back of the tongue are called 'circumvallate papillae' and contain taste buds. There can also be lingual tonsils, which are rounded masses of lymphatic tissues. These lingual tonsils are also found on the same region as that of the circumvallate papillae. Even though these bumps on back of the tongue are normal occurrences, but the appearance of these structures can be changed due to various reasons, which can include some medical conditions too. Here are some of the causes for big red bumps on back of the tongue.

Injury or Trauma
Injuries, like bites or burns, can cause large red bumps on the tongue. But as compared to the frontal part of the tongue, there are very less chances of the back side (of the tongue) getting affected by such injuries, which can be painful. In case of such injuries, large red bumps occur on the back of the tongue. These bumps can be treated with an antiseptic or saltwater mouth rinses, though these bumps heal naturally. Doctors may prescribe antibiotics to prevent any bacterial infection.

Allergies and Canker Sores
Large, red bumps on back of the tongue may be a result of some allergy, especially food allergies and those caused by some medication. Bumps due to allergies can appear on all parts of the tongue, the back side carrying the larger ones. While mild cases of swelling and hives are treated with antihistamines, severe swelling needs immediate medical attention. Canker sores can appear on any part of the tongue or mouth. The unusually large bumps on back of tongue can be canker sores, which can be left to heal naturally. It can also be treated with saltwater rinses for faster healing.

Kawasaki Disease and Warts
Another uncommon and rare cause for bumps on back of the tongue is an autoimmune disease, which affects children. This condition, which is called 'Kawasaki disease', is characterized by large, red bumps on the back side of the tongue. Even though very little is known about this condition, which can cause the tongue to turn a deep red, it is considered fatal for the affected child, if left untreated. The large bumps on back of the tongue can be warts too. These warts are of two types - ordinary ones, transmitted by sucking of fingers with warts and genital warts, transmitted through oral sex with a person who has active genital warts. Warts are similar to bumps in appearance and can be removed.

Bumps on back of tongue are a relatively uncommon thing. Though there are some larger bumps on back of the tongue, which are normal, most people are unaware of this fact. They start panicking, once they notice these projections. If you notice larger bumps which are red in color, on the back of the tongue, then wait for a few days. If these bumps do not disappear within a few days, you can consult a doctor at the earliest.
