Thank you for letting me know of your experience. I must say I'm relieved to learn I'm not the only one, though sorry you've dealt with it also. The pain was so bad it woke me up at 6:00am one morning, and another morning at 2:00. I was in tears. Luckily, it comes and goes.
So yes, if someone knows the cause, plese let us know!
The good thing is the pain prompted me to start the dental adventure I've been putting off forever. And actually, I'm beginning to suspect my dental problems are partially responsible for my overall health problems. Bleh.
