15671 Trigeminal Neuralgia Tn
Informed by recognized medical guidance
Overview
Trigeminal neuralgia is a condition that causes sudden, severe pain in parts of the face, like a sharp electric shock. It happens when the trigeminal nerve, which sends messages between the brain and the face, is not working properly. The pain usually affects one side of the face and can be triggered by everyday things like touching your face, brushing your teeth, or even a light breeze.
Key facts
- The pain is often described as sudden, sharp, shooting, or electric-shock-like.
- It usually affects one side of the face, most often the cheek, jaw, teeth, or gums.
- Episodes can come and go, and some people have long pain-free periods.
Trigeminal neuralgia is not very common. It is thought to affect about 1 in 15,000 people each year.
It can affect anyone, but it is more common in people over 50 and in women.
Symptoms
- Sudden, very severe facial pain along with weakness or numbness on one side of your face
- Difficulty speaking, confusion, or vision changes
- Pain that starts after a head injury
- ⚠Facial pain that is constant or lasts longer than a few minutes at a time
- ⚠Pain that is so severe you cannot eat or drink
- ⚠Pain accompanied by fever, rash, or swelling
Common symptoms
- Sudden, intense facial pain that lasts from a few seconds to a couple of minutes
- Pain that feels like an electric shock, stabbing, or burning
- Pain in the cheek, jaw, teeth, gums, lips, or, less often, around the eye or forehead
- Pain triggered by touching your face, brushing your teeth, eating, drinking, talking, or even a cool breeze
- Pain on one side of the face, rarely on both sides
Symptoms in children
- Trigeminal neuralgia is very rare in children, but when it happens, the symptoms are similar to adults: brief, sharp facial pain that may come and go.
Symptoms in older adults
- Older adults may mistake trigeminal neuralgia for dental problems, because the pain often occurs in the jaw or teeth. Seeing a healthcare provider is important for a correct diagnosis.
Causes
Main causes
- A blood vessel pressing against the trigeminal nerve inside the skull
- Damage to the nerve from a condition like multiple sclerosis
- Sometimes no clear cause can be found
Risk factors
- Being over 50
- Being female
- Having multiple sclerosis
- Having high blood pressure
When to see a doctor
See a doctor urgently if:
- If you experience sudden, severe facial pain that is unlike anything you have felt before, seek medical advice promptly.
Book a routine appointment if:
- If you have facial pain that keeps coming back, or if it is affecting your daily activities, make an appointment with your healthcare provider.
Diagnosis
A healthcare provider will ask about your symptoms and do a physical and neurological exam. If needed, they will refer you to a neurologist, a doctor who specializes in nerve problems.
Tests that may be done
- A neurological exam to check how your face responds to touch and sensation
- An MRI (magnetic resonance imaging) to look for anything pressing on the nerve, such as a blood vessel or tumor
What to expect at your appointment
Your provider will ask you to describe your pain in detail. Keeping a record of when the pain happens and what triggers it can help make the diagnosis easier.
Treatment
Treatment aims to reduce pain and improve quality of life. It may include medication, procedures, and in some cases, surgery. Your plan will depend on how severe your pain is and what is causing it.
Self-care at home
- Avoid touching your face when you do not need to
- Use gentle strokes when washing or applying lotions or makeup
- Try eating soft foods and chewing on the side of your mouth that feels better
- Keep a diary of your triggers so you can avoid them
Medical treatments
Your doctor may prescribe medicines that calm overactive nerve signals. These are not regular painkillers, and they must be taken exactly as prescribed. If these medicines do not work well or cause side effects, there are other procedures, such as nerve blocks, that your specialist can discuss with you.
When is surgery considered?
If pain is severe and medicines are not helping, surgery can be an option. There are different types, including procedures to take pressure off the nerve or prevent it from sending pain signals. A specialist will explain the options and help you decide what is best for you.
Living with this condition
Living with trigeminal neuralgia can be challenging, but many people learn to manage well. Knowing your triggers and taking pain medicine as prescribed can help you keep your daily routine.
Lifestyle tips
- Get enough rest, because tiredness can make pain worse
- Try relaxation techniques such as deep breathing or gentle yoga
- Talk to people you trust about your experience
- Ask for help when you need it
Diet and exercise
A soft, balanced diet can help if chewing hurts. Gentle exercise, like walking, can improve your overall wellbeing, but avoid pushing yourself too hard.
Mental health and emotional wellbeing
Living with chronic pain can sometimes lead to anxiety or depression. It is important to speak openly with your healthcare provider about how you feel. If you are struggling, reach out for support from a mental health professional.
Prevention
Trigeminal neuralgia cannot always be prevented, but you may be able to reduce the number of pain attacks by avoiding your known triggers, such as certain facial movements or foods.
Complications
If left untreated
- Severe pain can make it hard to eat, drink, or brush your teeth, which may lead to weight loss and poor nutrition
- It can make daily activities difficult and lead to anxiety, depression, or social withdrawal
Long-term outlook
With the right treatment and support, most people find significant relief. Many have long pain-free periods, and surgery can be effective if medicines are not enough. Trigeminal neuralgia is not life-threatening, and there are many options to help you live comfortably.
