Trigeminal Neuralgia is a condition that causes painful sensations similar to an electric shock on one side of the face.
This condition affects the trigeminal nerve, which carries sensation from your face to your brain. Some patients may experience:
In most cases, the cause is a loop of an artery lying in contact with the trigeminal nerve just as it approaches the brain stem. In some cases, the cause is a tumour (usually benign). In this case, surgery is often recommended.
There are no specific diagnostic tests for trigeminal neuralgia, and symptoms can be similar to other facial pain disorders. Therefore, it is vital to seek medical care if you experience unusual, sharp pain around the eyes, lips, nose, jaw, forehead and scalp, especially if you have not had recent dental or other facial surgery.
There are several effective ways to alleviate the pain, including various medications. Surgical treatment via a craniotomy may be considered if medications are ineffective. Surgery can relieve pressure on the trigeminal nerve from a nearby blood vessel and can be diagnosed with an MRI.
