Look at the picture of the white thing on the throat wall. You can look at Baidu pictures, which are rich in picture resources.

The white thing on the throat wall may be:

1, lymphofollicular hyperplasia of posterior pharyngeal wall:

First of all, we must judge the position of rice grains. If the rice grain is located in the posterior pharyngeal wall, we can generally judge that it is caused by the proliferation of lymphatic follicles in the posterior pharyngeal wall, mainly because chronic inflammation stimulates some white follicles to protrude from the mucosal surface. Often manifested as sore throat, dry throat, foreign body sensation in the throat and other symptoms.

2, tonsil stones:

If it is something the size of a white rice grain on the surface of the tonsil, we can judge that it may be a tonsil stone, mainly because there are some food residues left in the tonsil recess, but this is a white rice grain formed by bacterial decomposition, which may be accompanied by a little odor.
