Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that thee is inflammation of the circumvallate papilla which can be either due to infection or due to eating some hot food stuff or very hot fluid leading to inflammation and there can be secondary bacterial infection also along with inflammation..
You need not to worry and take
Amoxicillin 500 mg thrice a day for 5 days.
Take
Ibuprofen 400 mg thrice a day for relieving pain and inflammation..
Do warm saline gargles..
Gargle with a numbing solution can be relieving especially during meals..
Avoid hot,spicy and hard foods and take a soft and cool diet..
Sucking ice pops can relieve..
In case if the condition does not resolve consult an oral physician and get evaluated..
Hope this information helps..
Thanks and regards..
Dr.Honey Nandwani Arora..
