Thanks for writing your query.
You can take pain killer like Ibuprofen
one tablet twice a day after meals along with an antacid
You should keep the local area clean to prevent any secondary infection.
Local application of cream containing antibiotics like Neomycin
, Polymyxin B
and zinc will help in healing of the wound faster.
If the problem persists,you can get yourself examined clinically.
I hope this is helpful to you.
