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.
A variety of triggers may set off the pain of trigeminal neuralgia, including:
- Touching your face
- Brushing your teeth
- Putting on makeup
- Encountering a breeze
- Washing your face
