I have the same thing.I get seasonal allergies and it's particularly bad this year.It comes and goes so I am assuming it's not a tooth.When my nose runs it goes away.
Sounds like sinues to me. I have had the same problem. Do you have alergies? Your sinues are all around your face. I have had horrible tooth pain also and it was just my sinues again. Don't worry but have a Dr. check it out for you.
