Neuralgia

Neuralgia is one of the common symptoms of neurology. This kind of pain refers to the pain that is felt without external stimuli. There are many types of spontaneous pain, which can be divided into peripheral neuropathic pain and central neuropathic pain according to the site of the lesion. Those with unknown etiology are called primary neuralgia, and those with clear etiology are called secondary (or symptomatic) neuralgia. The lesion can be in the nerve root, plexus or nerve trunk. Often named after the peripheral nerve involved in the lesion. Local pain caused by other local lesions stimulating peripheral receptors and physical pain caused by sensory pathways in the central nervous system do not generally belong to the category of neuralgia.
