In the innermost part of the tongue, there are mushroom-like bumps on the surface of the tongue root, which are actually normal structures called contour papillae. When the tongue becomes inflamed, the contour papillae increase in size and are felt by the patient, but normally the contour papillae are not felt. In case of inflammation of the contour papilla, the patient can feel the foreign body sensation. Usually, anti-inflammatory drugs can be applied to the surface of the contour papilla to eliminate the inflammation, and nowadays, you can choose to use a throat-opening sword spray or a stomatitis spray.
