Hi..
Welcome to HEALTHCARE MAGIC..
As per your complain cuts and sores on tongue after consuming specific foods does not need to be necessarily due to
pancreas issue, rather it can be due to
Allergic Reaction and as it is after eating certain foods it comes under food allergies..
I would suggest you to consult an Allergist and get allergic tests like
Patch test, RAST test, food challenge test etc can help in diagnosis and treatment can be done accordingly..
The tests will help in ruling out the exact cause of the allergen and once you know the cause of the allergic reaction you can avid exposure to it to prevent allergy attack..
He can be advised to take anti allergics like
benadryl to relieve the symptoms..
Gargling with numbing mouthwash containing Lignocaine can relieve soreness..
Suck ice pops..
He can also be instilled an
Immunotherapy that will help in reducing the severity and frequency of allergic attack..
Once the allergen is ruled out avoiding exposure to it can prevent the allergy symptoms..
Hope this helps..
Regards..
