Thanks for the query.
You might have developed bacterial abscess
it is called as furuncle
It is a deep abscess and is very painful.
Pain can be there on entire face, as the nerve
supply of entire face is same.
A photograph would have helped me better.
Treatment is with antibiotics.
Please meet a dermatologist
for exact diagnosis.
