Trigeminal neuralgia is the most common brain nerve disease when the attack is unbearable for many patients. Therefore, it is important for patients to receive treatment at a regular hospital as early as possible. Therefore, it is important for people to understand the method of diagnosing trigeminal neuralgia in advance in order to cooperate with the treatment as early as possible. So, then how do we diagnose trigeminal neuralgia? 1. Nature of pain: The nature of pain in patients with trigeminal neuralgia mainly has five categories, namely, needle-like pain, knife-like pain, burning-like pain, tearing-like pain and electric shock-like pain. 2, pain site: the pain site of trigeminal neuralgia will gradually spread from the face, mouth or a point of the jaw to the trigeminal nerve, the second branch of the nerve, the third branch is the most common, the pain range will not exceed the midline of the face, generally the right side of the face pain is more common. Pain trigger points: Trigeminal neuralgia has obvious pain trigger points, often located in the nose, upper lip, gums, tongue, corners of the mouth, eyebrows, etc. Light touch or stimulation of the trigger points may stimulate the onset of pain. 4, the pattern of pain: Although the onset of trigeminal neuralgia without warning, sudden stop will also be sudden attacks, but the pain symptoms have a certain pattern, that is, each time the pain is short, mostly in a few seconds to within 2 minutes suddenly stop, and the early onset of pain is less, the interval is longer, with the development of the disease, the number of pain will become more and more frequent, the interval is shorter and shorter, the pain is gradually increased. In addition, the pain symptom of trigeminal neuralgia rarely attacks at night, and there is no discomfort during the interval. The above is to introduce the diagnosis of trigeminal neuralgia, hope to bring help to the treatment of patients, if you find yourself suffering from trigeminal neuralgia should go to the hospital for treatment in time.
