Neuralgia
Alternate Names : Nerve pain
Symptoms & Signs
- Impaired function of affected body part due to pain, or muscle weakness due to motor nerve damage
- Increased sensitivity of the skin or numbness of the affected skin area (feeling similar to a local anesthetic, such as a Novocaine shot)
- Pain along the path of a specific nerve
- Pain located anywhere, usually on or near the surface of the body
- In the same location for each episode
- Sharp, stabbing pain that comes and goes (intermittent) or constant, burning pain
Any touch or pressure is felt as pain. Movement may also be painful.
Diagnosis & Tests
An exam may show: - Abnormal sensation in the skin
- Loss of deep tendon reflexes
- Loss of muscle mass
- Lack of sweating (sweating is controlled by nerves)
- Tenderness along a nerve, often in the lower face and jaw and rarely in the temple and forehead
- Trigger points (areas where even a slight touch triggers pain)
A dental examination can rule out dental disorders that may cause facial pain (such as a tooth abscess). Other symptoms (such as redness or swelling) may help rule out conditions such as infections, bone fractures, or rheumatoid arthritis. There are no specific tests for neuralgia, but the following tests may be done to find the cause of the pain:
