Trigeminal neuralgia is a severe neuropathic face pain caused by the trigeminal nerve, which is positioned right behind the jaw and close to the temporomandibular joint. This nerve is divided into three branches that carry sensations from the mouth and face to the brain. There are numerous possible reasons for what causes trigeminal neuralgia to flare up, however, the precise reason is frequently unclear.
One of the most common causes of trigeminal nerve pain is due to the compression of a blood vessel in the trigeminal nerve. This sort of compression is more prevalent in elderly people. Destruction of the trigeminal nerve is another possibility. This is less prevalent, although it may happen to anyone at any age.
Trigeminal neuralgia or TN attack can be caused by a variety of factors, including:
- Pressure on the trigeminal nerve, usually by a blood vessel that exits the brain stem and erodes the protective covering around the nerve (the myelin sheath), causes irritation.
- Myelin deterioration, caused by multiple sclerosis, is known as a kind of demyelinating disease.
- A tumor on the trigeminal nerve may compress it.
- An arteriovenous malformation is a condition in which blood vessels and arteries are tangled.
- Sinus surgery, oral surgery, stroke, or facial trauma can all damage the trigeminal nerve.

What Are The Causes Of Trigeminal Neuralgia?
The fact that living with trigeminal nerve neuropathy is difficult stems from the fact that it is usually routine daily activities that trigger the condition to flare up. This is why many doctors will recommend therapy, since avoiding regular activities might be both tough and inconvenient. Trigeminal neuralgia has a wide range of triggers, each with its own set of symptoms. Trigeminal neuralgia attacks can vary from person to person, but certain activities that trigger acute episodes are common:Certain Foods
Caffeine, sweets, and hot foods could be aggravating for certain individuals. These might activate the trigeminal nerve branches that supply sensation to the mouth’s inner surface, or they may be due to how these meals interact in the body.Extreme Weather Changes
For some people, drastic changes in temperature (either hot or cold) may cause trigeminal nerve pain symptoms, eventually building toward a full-fledged attack.Physical Activity
Recreational activities such as jogging, playing tennis, or even sexual intercourse could trigger an episode of trigeminal neuralgia. In some cases, simply brushing your teeth could set off the pain.Bending Over
The act of bending over is generally not problematic for most people. However, for those with trigeminal neuralgia, this could put extra pressure on the trigeminal nerve and irritate it, leading to an attack.Shaving
Like brushing your teeth, shaving is a regular morning activity for many men. Unfortunately, the act of shaving can also lead to a trigeminal neuralgia attack in some men.Applying Makeup
For women, applying makeup is another daily activity that could potentially trigger an episode of trigeminal neuralgia. In particular, mascara and other products that are applied close to the eye area may be more likely to set off the pain.Blowing Your Nose
Again, this is a common daily activity that most people don’t think twice about. However, for those with trigeminal neuralgia, blowing your nose can put pressure on the trigeminal nerve and cause an attack.Yawning or Sneezing
These are both natural reflexes that we often cannot control. Unfortunately, they can also lead to trigeminal neuralgia pain in some people.Alcohol
Alcohol has blood vessel effects as well, leading to dehydration and worsening. Trigeminal neuralgia may be triggered by either of these factors.Smoking
Like alcohol, smoking has blood vessel effects that can lead to trigeminal neuralgia pain. Smoking also causes dehydration, which can trigger an attack.
