had a tooth pulled five months ago, two days ago started having horrible gum, jaw pain in the area. i'm on antibiotic 500mg amox tid....no fever, take advil and Celebrex for pain without relief. it throbs to my pulse, entire left side of face hurts...I have very high tolerance to pain, I refuse to crowd a er with tooth pain...my only concern is it being a serius infection that goes to my brain
