Numbness of the face occurs due to some condition of the Trigeminal nerve. Some of the conditions which can affect it are:

Infections: Infections such as Herpes zoster, Lyme disease, Sarcoid disease may cause numbness of this nerve. MRI of the region will usually show thickening of the nerve. An LP with cytology may be helpful.

Pressure: any cause of pressure on the nerve, such as with increased intracranial pressure, as in Benign Intracranial Hypertension. This will show up in an MRI.

Arnold Chiari malformation: this may also cause kinking of the nerve.

Tumours: Tumours along the course of the nerve, from the pons to the periphery.

Migraines: A type of migraine without the associated headache, called 'migraine equivalents' may cause such symptoms. There are no specific tests for this, but trial with an anti-migraine drug will confirm this.

Somatisation: Finally, and most importantly, stress, depression, etc, can be the cause of this. If all others are ruled out, this is the condition to consider.

You should approach a Neurologist. He will need full neurological testing for reflexes such as the corneal reflex. He may also need an MRI and EEG. You can discuss these conditions with you neurologist.
