There are a lot of small bubbles in the throat, it is difficult to determine the disease based on this symptom, it is recommended that the patient consult a doctor in time to find out the cause of the disease; it may be chronic pharyngitis or reflux pharyngitis caused by mucosal hyperplasia of the posterior wall of the pharynx or lymphoid follicular hyperplasia. Small bubbles inside the throat are usually caused by chronic pharyngitis, which stimulates the mucosa of the posterior pharyngeal wall, leading to hyperplasia of the mucosa of the posterior pharyngeal wall and the appearance of lymphoid follicles. It may also be the reflux pharyngitis attack, gastric acid stimulation of the mucous membrane of the pharynx, mucosal edema and lymphoid follicular hyperplasia in the pharynx. In addition to the above factors, we can not rule out other factors, such as herpes pharyngitis, pharyngeal fungal infections, etc.; we should consult a doctor in time to clarify the cause and take active treatment.
