### input:
I have had blisters off and on during the day in my mouth. In the evening I have a build up of mucous in the top of my mouth. So far an ENT prescribed a numbing mouth wash so I wouldn t be bothered. But it isn t going away. My MD says my blood work is normal but obviously I either eat too high acidic foods or I have developed an allergy to something. I just need to find out how to go about going in the right direction to end this. If I suck on a choraseptic losenger the blisters go away for over an hour. Can you suggest what I should do to get help? I am a nutritionist with a PHD and a lifelong vegetarian. I don t eat junk and limit dairy except cheese on my salads. So my doctors suggestion to eat less acidic food doesn t fly.

### output:

Hi. Thanks for the query. Blisters in mouth along with mucous build up can be due to causes like acid reflux, sinus infection, oral and throat infection, allergies etc. Another common cause for sores in mouth can be herpes simplex virus infection causing cold sores. So my suggestion is to consult an Oral Physician and get a thorough clinical examination done along with a blood test to check for allergies as well as viral infection and also get a mouth swab culture done. Treatment can be planned once the exact cause is ruled out. For now, you should continue to suck Choraseptic lozenges and along with it do war saline gargles. Avoid spicy foods. You can also gargle with 1:1 solution of Betadine and milk of magnesia. Hope this helps. Regards.
