A lot of blister-like things in the throat are most likely lymphatic follicles on the back wall of the patient’s throat, sometimes they look small, sometimes they can be very large, mainly influenced by the patient’s mood factors, as well as living habits and eating habits. If the patient smokes a lot, drinks alcohol or stays up late, the lymphatic follicles will increase significantly and many small transparent blisters will be found after opening the mouth. Sometimes patients are worried, but they are actually lymphatic follicles on the back wall of the patient’s throat, which mainly play a certain immune function. If the patient eats stimulating food, the lymphoid follicle proliferation will be obvious due to the immune, stressful effect. Therefore, it is recommended that patients should not be particularly worried, and actively regulate their dietary habits and lifestyle habits, and the small blisters on the back wall of the throat should gradually subside. However, they will not all subside because they are normal lymphoid tissue and may be scattered on the mucosa of the posterior pharyngeal wall.
