Trigeminal Neuralgia is a chronic pain condition that affects the trigeminal nerve, which carries sensation from your face to your brain. If you have trigeminal neuralgia, even mild stimulation of your face — such as from brushing your teeth or putting on makeup — may trigger a jolt of excruciating pain.
Trigeminal neuralgia symptoms may include one or more of these patterns:
- Episodes of severe, shooting or jabbing pain that may feel like an electric shock
- Spontaneous attacks of pain or attacks triggered by things such as touching the face, chewing,
- speaking or brushing teeth
- Bouts of pain lasting from a few seconds to several minutes
- Episodes of several attacks lasting days, weeks, months or longer — some people have periods
- when they experience no pain
- Constant aching, burning feeling that may occur before it evolves into the spasm-like pain of
- trigeminal neuralgia
- Pain in areas supplied by the trigeminal nerve, including the cheek, jaw, teeth, gums, lips, or less
- often the eye and forehead
- Pain affecting one side of the face at a time, though may rarely affect both sides of the face
- Pain focused in one spot or spread in a wider pattern
- Attacks that become more frequent and intense over time
In trigeminal neuralgia, also called tic douloureux, the trigeminal nerve’s function is disrupted. Usually, the problem is contact between a normal blood vessel — in this case, an artery or a vein — and the trigeminal nerve at the base of your brain. This contact puts pressure on the nerve and causes it to malfunction.
Trigeminal neuralgia can occur as a result of aging, or it can be related to multiple sclerosis or a similar disorder that damages the myelin sheath protecting certain nerves. Trigeminal neuralgia can also be caused by a tumor compressing the trigeminal nerve.
Some people may experience trigeminal neuralgia due to a brain lesion or other abnormalities. In other cases, surgical injuries, stroke or facial trauma may be responsible for trigeminal neuralgia.
