I know right away if im going to slime and pb because my jaw aches like crazy! Does this happen to anyone else?

same here!! I think its gas or air trapped in your jaw!!

same here. There's nowhere in your jaw for air to get trapped, it must just be referred pain. The roof of my mouth can ache too.

Maybe from the building pressure......

Not saying it is the same, but jaw pain is also a sign of heart attack, so I was thinking, the building pressure, may trigger it.....but it is nothing more than an uneducated guess---my best kind!!!

But in answer to the question----yep me too!
