What is the cause of a small, rice-like lump in the mouth of the throat that doesn’t hurt?

The mouth of the throat has millet grain-like lumps but does not hurt, may be tonsil stones, the posterior wall of the pharynx lymphoid follicular hyperplasia, and so on.
1. Tonsil stones: due to the repeated stimulation of chronic tonsillitis leading to tonsil hyperplasia, tonsil crypts on the long-term obstruction of the tonsils, poor drainage of secretions, caseous material accumulation, thus forming tonsil stones. It can be manifested as a small rice grain-like lump in the throat but not painful.
3. Lymphoid follicular hyperplasia of the posterior wall of the pharynx: Due to repeated inflammatory stimulation of the pharynx, the posterior wall of the pharynx has a granular bulge or even fused into a piece. It can also be manifested as millet-like lumps in the throat, often without pain.
When you find a small granular lump in the throat, go to the hospital in time to clarify the cause of the disease and carry out standardized treatment under the guidance of the doctor.
