Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have a
Canker Sore that seems severly inflamed and infected leading to pain..
It can occur due to a number of causes like deficiencies of Iron and
Vitamin B12, stress, physical trauma,
acid reflux, etc..
You can first of all start applying a numbing gel containing Lignocaine over the Ulcer as it will numb the area and provide relief..
You can take anti-inflammatory painkiller like
Ibuprofen..
You can take a
multivitamin tablet for atleast 15 days.
You can suck ice or do cool water rinses to reduce inflammation and ultimately pain..
You should take a soft and light diet..
In case if still it does not improve consult an Oral Physician and get evaluated..
Hope this information helps..
Thanks and regards.
