Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain a painful bump at the back of the mouth along with a recent history of
sore throat can be due to causes like
Pyogenic Granuloma, Abscess, apthous ulcer or
canker sore etc..
Nothing to worry as it will resolve soon..
You can start gargling with a numbing mouthwash containing Lignocaine..
You can gargle with betadine solution by putting few drops of betadine solution in water..
You can take anti-inflammatory painkiller like Ibuprofen..
You can take a
soft diet and avoid spicy food to prevent its irritation..
Drink plenty of water..
In case if it still does not improve in a week consult an Oral Physician and get evaluated and you can be advised a course of
oral antibiotics along with other remedies as advised..
Hope this information helps..
Thanks and regards.
