Hi Kirstee, the tongue thing must have been an absolute nightmare! Great news you have it under control now.
My jaw has developed a vibration feeling on biting my teeth together - subtle, but it has the feeling of the teeth shaking together on the bite. I have TMJD which messes up the right hand side of the jaw - the muscle twitching on that side was one of the first symptoms I noticed back in June. Drs love telling us it's stress but I've had a hell of a lot worse stress in my life before this all started.
