Hi..
Welcome to HEALTHCARE MAGIC..
As per your query the symptoms are pointing towards inflammation of the mucous membranes of mouth and can occur due to a number of causes like Allergy to certain medicines,
dry mouth, oral infections like thrush, deficiency of
vitamin b12 and iron,
hormonal imbalances,
diabetes, dry mouth etc..
At times there is no known underlying cause and it is Idiopathic in nature..
You should consult an oral physician and get evaluated and treatment of underlying cause will relieve the symptoms..
As of now you can start supportive therapy like gargling with numbing mouthwash containing Lignocaine for pain relief during meals..
Take a
multivitamin tablet daily.
For reducing inflammation take anti-inflammatory medicine like Advil, do cold water rinses and suck ice pops..
Avoid hot and spicy foods..
If you experience dry mouth chew sugar free chewing gums as it will help in stimulating saliva flow..
Avoid stress..
Drink plenty of water..
Hope this information helps..
Thanks and regards..
