Harmless Tonsillar Cyst
This indicates a harmless nodule. This is a fluid-filled mass. It will rupture by itself and the fluid can be swallowed. The cause of this nodule is a blockage of a gland opening, causing a cyst. This can become quite large with time. If it causes no pain, no treatment is required. Stop putting your tongue out and examining your throat each time you get hold of a mirror. Formation of more than one cyst can lead to swollen tonsils that require surgical removal.
