[|AI|]  Hi Dear, As per symptoms in the query it seems like these blisters could be due to an infection, Irritation to mucosa due to hot and acidic food, reaction to medications or immune deficiency. Consult ENT specialist, doctor would evaluate for these three causes. Doctor would recommend a complete blood count which includes your white blood cell counts, differential counts and Erythrocyte Sedimentation Rate (ESR). This will give us the nature of the infection (viral or bacterial). An examination of your Paranasal sinuses is also indicated since recurrent post nasal Chat Doctor.  Doctor would also like to evaluate the list of medications that you have taken recently Do warm saline gargles 2-3 times a day. Also do Betadine gargles one a day. Quit tobacco as this exaggerate the condition and does not let it heal properly. . Hope your concern has been resolved.
