What can cause tingling / numbness in left cheek and lips?

Comments. The anatomy involves trigeminal nerve, but the cause may be complex. There is a sensory trigeminal neuropathy which could do this, but one might consider problems in jaw or mouth as a provocateur. Some intracranial situations should be excluded via MRI. A neurologist or a dentist could be a starting point.
