Hi..
Thanks for writing to us..
It seems that you are suffering from RECURRENT APTHOUS ULCER which is causing you the eruption of painful mouth ulcers or sores..
It can be caused due to a number of reasons like Stress,
Nutritional Deficiency [Iron, Vitamin B12 and Folic acid] , hormonal changes, acid reflux, tongue trauma due to some sharp teeth or tongue biting habit, excessive intake of sour and citrus foods,
uncontrolled diabetes and other immunocompromised conditions etc..
You need to consult an Oral Physician or a general
dentist in this regard to get evaluated and treated..
For apthous ulcer you can do warm saline gargles
Gargles with 1:1 solution of benadryl and
milk of magnesia can help..
Continue to apply numbing gel over the sore for relief from pain especially during eating..
Continue to take
multivitamin tablet like Zincovit for a period of 15 days and also continue other medications as advised..
Avoid spicy, sour and acidic foods..
In case if still the condition does not subside the physician can prescribe you to take a Steroid course as it it the ultimate treatment in case if nothing else works..
Hope this information helps..
Regards..
