Yes I have real bad jaw pain it starts on the bottom then the whole cheek and top of jaw hurts, last couple of days at least twice a day, now it is happening more than twice, I can't get to see my dentist until tomorrow, I don't know why they wont see me sooner. anyways I am taking Advil every four hours and it still hurts a lot where I have to put my heating pad on my jaw. What could this be?
