My eye has been twitching all the time. Since the twitching started my jaw also keeps locking. Most if the time my eye will be twitching, my teeth will start to grind and while my teeth are grinding my jaw will start to lock up. What is going on with me?

Is there any pain?

There are some common conditions involving the nerves of the face that affect the eyes or jaw or both. It can even be simple stress.

The trigeminal nerve is 3 separate branches - forehead/eye region, cheek and upper lip, and lower jaw, which join together as they travel back to the brain.
Trigeminal neuralgia always involves PAIN, but there are countless other conditions that can affect the nerves in the face.

See a dentist, for starters.

I'd have immediately gone to a doctor if I experienced those symptoms.
