I've had 3 tmj surgeries and during the last one the doctor severed my trigeminal nerve. This is the main nerve that controls your face. Immediately after surgery I lost all function in the left side of my face. Over the years it has improved and eventually I just have a deading feeling across my jawline. Two days ago I got a horrible pain in face, shooting across my eye and jawline. My face felt normal for about 30 seconds and then went back to feeling odd. Has anyone experienced this, or have any idea about it? I'm assuming the nerve is actually trying to grow back, thus the electric shock, but not sure.
