Why is your jaw pulsating and ear cracking on the same side?

because you are a weird little thing.

USUALLY, THAT SIGNALS THE START OF AN EAR INFECTION ...

YOUR EUSTACHIAN TUBES ARE BLOCKED & YOU BODY IS TRYING TO RE ADJUST THEMSELVES... TO THE CHANGE IN YOUR EAR PRESSURE...

IT ALSO MEANS A TRIP TO THE DR'S AS IT DOESN'T WORK!
