It is possible you have an abscess or cyst in your back teeth. Effects the mandibular nerve (tongue) I would go to a Dentist or doc straight away.
Means your body is trying to tell something isn't right. LIke everyone else said and i see you did. Call 911 because it's not something you should ignore.
Could be either. I am an epileptic as well, and just had a huge seizure a couple of weeks ago. I found myself face down in the dirt, with my whole left side feeling numb. Check in with your neurologist asap.

You must ask questions - otherwise they don't tell you anything. Ask, ask, ask. Make them explain it to you until you understand it. Best to you.
