Inflammation of the throat: acute tonsillitis, acute pharyngitis and other inflammatory diseases of the throat can lead to diffuse congestion of the mucosa of the pharynx and the mucosa of the palate, enlarged tonsils, dilated blood vessels in the posterior wall of the pharynx, oozing, and obvious edema of the mucosa, which can lead to the symptom of swallowing saliva and feeling of the palate being swollen. 3. Oral inflammatory diseases: periapical periodontitis, gingivitis, periodontitis and other oral inflammatory diseases will stimulate the capillaries of the palate, resulting in vasodilatation, which will cause the palate to feel swollen. 4.
