My back right gum (where my wisdom tooth should be) hurts very bad to the finger touch or when I chew back there. I m 18, turn 19 exactly in one month, I m a guy. It started 3 days ago, pain hasn t seemed to get worse or better. If I take my index finger and press down it hurts very bad and if I chew something there it hurts extremley bad as well. A very sore black and blue type of pain. There is literally only gum there, the tooth hasn t even pricked up yet. Did I just injure my gum, or is the tooth trying to come up?
