Shooting Jaw Pain (Trigeminal Neuralgia)

25/09/2020

Trigeminal Neuralgia or also known as Tic Douloureux is a sudden and severe facial pain. The term neuralgia refers to severe pain along the course of a nerve due to nerve irritation or damage. Trigeminal Neuralgia affects the trigeminal nerve which is one of the most wide-reaching nerves in the head.

This pain is often described as sharp shooting pain or an intense electric shock, causing it to be one of the most known excruciating pain. It usually happens in short and unpredictable attacks that can last from a few seconds to about 2 minutes. The attacks stop as suddenly as they start. The pain can be triggered by simple activities such as brushing teeth, washing face, shaving or putting on makeup. Even a light breeze against the face might set off the pain.

In most cases, trigeminal neuralgia affects just one side of the face with the pain usually felt in the lower part of the face. Very occasionally the pain can affect both sides of the face although not usually at the same time. When that happens, it is called Bilateral Trigeminal Neuralgia.

So what causes Trigeminal Neuralgia?

There are 12 pairs of cranial nerves in the human head. The trigeminal nerves are among these pairs which allow sensations to be felt in the face. One nerve runs down each side of the head.

Each trigeminal nerve splits into three branches which control the feeling for different parts of the face.

  • The ophthalmic branch controls the eye, upper eyelid and forehead.
  • The maxillary branch affects lower eyelid, cheek, nostril, upper lip and upper gum.
  • The mandibular branch runs the jaw, lower lip, lower gum and some muscles used for chewing.

The disorder can affect any of the three nerve branches which means that the pain can be felt from the forehead to the jaw.

The cause of trigeminal neuralgia often starts with irritation of the trigeminal nerve caused by a tumour, tangle of arteries or blood vessels pressing on the nerve which damages the protective coating around the nerve called the myelin sheath. Certain diseases such as multiple sclerosis can also injure the myelin sheath.

Physical therapy can help relieve the severity of symptoms with trigeminal neuralgia. To reduce muscle spasm, manual therapy and a hot moist pack will be applied on the neck and trapezius muscle. Isometric neck exercises for each side and pain-free neck range of motion exercises (neck flexion, extension, and side-flexion) will be prescribed. Relaxation techniques which include deep breathing exercise will also be taught by your therapist. If in doubt, seek professional advice.
