Several conditions may be associated with face pain. Nerves, muscles, tendons, and bones may be implicated. Infections, herpes, trauma, nerve damage, stroke, and surgery may be a cause. If nerves are causing the face pain, it may be a condition referred to as Trigeminal Neuralgia. Trigeminal neuralgia occurs when a blood vessel presses down on the nerve near the brain stem. Over time, changes in the brain’s blood vessels can result in them rubbing against the trigeminal nerve root. This rubbing eventually wears away the insulating membrane of the nerve and results in irritation.
Identifying the problem will help delineate therapy. Your doctor may choose a trial period of antineuropathics, opioids, or antidepressants. If medications fail some injections may be of benefit; including stellate ganglia, trigger point, and selected nerves such as facial, trigeminal, supraoptical, etc. As well as epidurals, TMJ, and facet joints.
