Neuralgia
Neuralgia is pain in a particular' and is due to nerve damage, irritation, or pressure. The pain usually lasts for only a brief period, but may be severe and is often described as a shooting sensation. It is a symptom of shingles, which is an infection of the nerves leading to areas of the skin; for instance, down one side of the trunk, neck or arm, or, more rarely, the face. Postherpetic pain, which is pain following a herpes zoster infection, is caused by damage to the nerves, which results in repeated, strong nerve impulses being produced and sent to the brain. The pain is severe and can last for weeks or months.

Treatment
Acupressure Trigeminal neuralgia, a spasmodic pain on one side of the face, can be self-treated by lightly pressing inward with the index fingers, just below the inner side of the brow, or from the same point, downward to the mouth. Neuralgia accompanying migraine can also be treated with light pressure or acupuncture.

Biofeedback and Homeopathy Remedies and biofeedback may be used to prevent stress, which may bring on attacks of neuralgia.
Acupuncture Particularly when used early on, this has been shown to prevent postherpetic neuralgia­following shingles.

Tens Transcutaneous Electrical Nerve Stimulation This therapy uses electrodes to block these nerve impulses and stimulate the release of endorphins, the body's natural pain-relieving hormones, and is also particularly useful for pain following an attack of shingles , and for other forms of neuralgia or face pain.

Aromatherapy, Chiropractic, Traditional Chinese Medicine, Hypnotherapy, Naturopathy, and Osteopathy have also proved beneficial.
