Trigeminal neuralgia is inflammation of the trigeminal nerve, causing intense facial pain.
The most frequent cause of trigeminal neuralgia is a blood vessel pressing on the nerve near the brain stem. Over time, changes in the blood vessels of the brain can result in blood vessels rubbing against the trigeminal nerve root. Trigeminal neuralgia affects the trigeminal nerve, one of the largest nerves in the head. The trigeminal nerve sends impulses of touch, pain, pressure, and temperature to the brain from the face, jaw, gums, forehead, and around the eyes. The pain of TN is from the trigeminal nerve. The trigeminal nerve is a paired cranial nerve that has three major branches: the ophthalmic nerve (V 1), the maxillary nerve (V 2), and the mandibular nerve (V 3). One, two, or all three branches of the nerve may be affected. Additional resources from MedlinePlus. Trigeminal neuralgia (TN), also called tic douloureux, is a chronic pain condition that causes extreme, sporadic, sudden burning or shock-like face pain. The pain seldom lasts more than a few seconds or a minute or two per episode. The intensity of pain can be physically and mentally incapacitating.  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 (TN), also called tic douloureux, is a chronic pain condition that affects the trigeminal or 5th cranial nerve, one of the most widely distributed nerves in the head. TN is associated with a variety of conditions. TN can be caused by a blood vessel pressing on the trigeminal nerve as it exits the brain stem. This compression causes the wearing away or damage to the protective coating around the nerve (the myelin sheath). Trigeminal neuralgia is inflammation of the trigeminal nerve, causing intense facial pain. It is also known as tic douloureax because the intense pain can cause patients to contort their face into a grimace and cause the head to move away from the pain. The obvious movement is known as a tic.  Knowledge center. Trigeminal Neuralgia, also known as Tic Douloureaux, is a nerve disorder that causes abrupt, searing, electric-shock-like facial pains, most commonly the pain involves the lower face and jaw, but symptoms may appear near the nose, ears, eyes or lips. 1 There is no facial weakness or numbness. 2  Atypical trigeminal neuralgia pain (Atypical facial pain-ATFP). 3  As well as extremely sharp, throbbing, and electric-shock-like, patients may experience other types of pain. 4  Their condition does not have just the hallmark symptoms of classic trigeminal neuralgia pain. Trigeminal neuralgia (TN, or TGN), also known as prosopalgia, tic doloureux, or Fothergill's disease is a neuropathic disorder characterized by episodes of intense pain in the face. It has been described as among the most painful conditions known. The trigeminal nerve is a paired cranial nerve that has three major branches: the ophthalmic nerve (V 1), the maxillary nerve (V 2), and the mandibular nerve (V 3). One, two, or all three branches of the nerve may be affected. Causes. The pain associated with trigeminal neuralgia represents an irritation of the nerve. The cause of the pain usually is due to contact between a healthy artery or vein and the trigeminal nerve at the base of the brain. This places pressure on the nerve as it enters the brain and causes the nerve to misfire. Trigeminal neuralgia, also known as tic douloureux, sometimes is described as the most excruciating pain known to humanity. The pain typically involves the lower face and jaw, although sometimes it affects the area around the nose and above the eye.
