Pain in short bursts: It lasts seconds to a maximum of minutes. Rarely more than 2 minutes. But it is EXPLOSIVE. It appears suddenly, without warning.
Electric pain: It feels like a lightning bolt, a shock, pure electricity. Burning. Sharp. Some describe it as if someone were stabbing you in the face.
Triggers: The pain is triggered by the smallest things. Touching your face. Talking. Chewing. Brushing your teeth. Even wind in your face. Some patients are afraid to eat because every chew triggers the pain.
Specific areas: It always hurts on the SAME side of the face. And in the SAME area — cheek, jaw, or forehead. It doesn’t move.
No symptoms between attacks: After the pain, you feel fine. Until it returns. It could be minutes or hours later.
It affects only one side: IMPORTANT: It’s always one side. If both sides hurt, it’s probably not trigeminal neuralgia.
Why It Happens (The Real Causes)
The most common cause is vascular compression . A blood vessel is rubbing against the trigeminal nerve. Every time your heart beats, the vessel rubs against the nerve. The nerve becomes irritated and sends a pain signal.
It’s like having an old telephone cable, and someone is constantly passing something over it. The cable gets damaged.
According to the MSD Manual for Professionals , the most frequent compression comes from an intracranial artery (such as the anterior inferior cerebellar artery) that rubs against the nerve in its entry zone to the brainstem.
Other causes:
Nerve inflammation: Sometimes a nerve becomes inflamed for no apparent reason. The inflammation causes irritation. The nerve becomes hypersensitive.
Previous scars or injuries: If you had a facial accident, surgery, or trauma — there may be a scar that presses on the nerve years later.
Multiple sclerosis: According to the University Clinic of Navarra , between 1 and 2% of patients with multiple sclerosis develop trigeminal neuralgia, which represents 2–3% of the total cases of this condition.
Tumor or injury: Rarely, a tumor presses on the nerve. But it is uncommon.
Unknown cause: In many cases, doctors find no cause. The nerve simply becomes irritable. No one knows why.
Why Almost No One Diagnoses It in Time
Most people with trigeminal neuralgia initially think they have a toothache. They go to the dentist. The dentist finds nothing wrong. They have the tooth extracted anyway (a common mistake).
The pain persists. First they think it’s sinusitis. Then a migraine. Then TMJ (jaw) pain.
YEARS go by before someone says “it’s trigeminal neuralgia.”
Why? Because it’s rare. And because the pain is so intense that people think there must be something visible—an infection, an injury, something. But with neuralgia, there’s nothing visible. It’s just an irritated nerve.
According to the consensus document of the Spanish Society of Neurology (SEN, 2023) , this condition is frequently confused with pain of dental origin, leading to unnecessary treatments and diagnostic delay.
Home Remedies That Actually Work
Here’s the important part: there’s no “home cure” for trigeminal neuralgia. BUT there are things that can RELIEVE the pain.
1. Cold Compresses (Immediate Relief)
The cold numbs the nerve. When you feel an attack coming on, place an ice pack wrapped in a towel on the painful area. Not directly on the skin—that will burn. Wrap it in a towel.
Hold for 10-15 minutes. The pain should decrease.
Why does it work? Cold slows down nerve conduction. The nerve temporarily “falls asleep.”
2. Deep Heat (For Relaxation)
Here’s the paradox: some patients respond better to HEAT than to cold. Apply a warm (not boiling) heating pad to the affected face for 15 minutes.
Heat relaxes the muscles around the nerve. If muscle tension is contributing, heat helps.
Experiment. If cold works for you, use cold. If heat works, use heat. Some of us alternate.
