1. Ask to say “ahhh” to check uvula elevation - Cranial nerve X (motor)
2. Ask to say “ahhh” to check constriction of posterior pharyngeal wall Cranial nerve IX (motor)
3. Stroke left or right pharynx to elicit gag reflex - Cranial nerve IX (viscerosensory) and Cranial X (motor)

This takes time and can cause a variety of unpleasant symptoms including tingling and pain. These symptoms are a good sign that the nerve is healing.

How does a neurologist check for nerve damage?

By measuring the electrical activity they are able to determine if there is nerve damage, the extent of the damage and potentially the cause of the damage. Frequently the neurologist will recommend common, noninvasive neurological evaluations such as electromyography (EMG) and nerve conduction velocity (NCV) testing.

Is Bell's palsy a mini stroke?
