The number of patients with trigeminal neuralgia is increasing, so what are the symptoms of trigeminal neuralgia? Trigeminal neuralgia is a neurological disease, and once you suffer from it, the symptoms start to appear and are very obvious. How much do we know about the specific symptoms of trigeminal neuralgia? The main symptoms of trigeminal neuralgia are in the following three aspects: 1. Facial symptoms When the attack occurs, half of the face can be spasmodically distorted, and sometimes sympathetic syndrome occurs after the attack is terminated, which is manifested by white face, then flushing, conjunctival congestion, accompanied by lacrimation, runny nose, salivation, etc. Sometimes there are so-called trigeminal, facial muscle spastic painful twitches and vegetative neurosis. This is the symptomatic manifestation of trigeminal neuralgia. 2.Degree of diffusion The spread of pain does not jump, such as the third branch of pain does not cross the second branch and go to the first branch of pain. The pain also does not cross the midline, and even in bilateral patients, one side of the attack does not cross the opposite side. The site of pain is one or several branches in the distribution area of trigeminal nerve, or it may start from one branch and spread to other branches.
