Here is a Question from Sarah Branam : What are these Muscle Spasms in the Jaw?
“My Boston, Preston has new onset muscle spasms in his jaw. I don’t know if that’s what it is– that’s just the only way I know to describe it.
It’s been happening for about a week, and my other Boston has been having it happen too. It’s kinda worrying me because it’s something new that I’ve never noticed before, and because both of them have been having them.”
