causes of neuralgia
Causes of Neuralgia. The underlying cause of any type of neuralgia is damage to a nerve. Each nerve in your body is protected by a coating called the myelin sheath. When the myelin is damaged or wears away from the nerve, the stabbing, severe, shock-like pain of neuralgia results.There are many different factors, including old age, which can cause damage to the myelin. Unfortunately, in many cases of neuralgia, a cause can never be found.he myelin on nerves can be worn away by pressure. The pressure may come from a bone, ligament, blood vessel, or a tumor that is pressing on the nerve. The pressure of a swollen blood vessel is a common cause in trigeminal neuralgia.
