Trigeminal neuralgia is clinically known as “painful spasm”, which is a disease that involves the face and is limited to one or several branches of the trigeminal nerve, and is the most typical neuralgia. Although the diagnosis of this disease is easy, many patients have been suffering from the disease for tens of years without being cured due to effective treatments such as nerve block, and the unbearable pain makes them suffer. For the convenience of treatment, trigeminal neuralgia is usually divided into primary (idiopathic) and secondary (symptomatic) types. (1) Secondary trigeminal neuralgia This disease refers to painful symptoms caused by lesions of the trigeminal nerve itself or adjacent tissues, but in addition to pain, there are also neurological signs, which can be secondary to tumors, vascular malformations, aneurysms, arachnoiditis and multiple sclerosis in the pontocerebellar angle, trigeminal roots or hemianopsia. (2) Primary trigeminal neuralgia Primary trigeminal neuralgia refers to those who do not show neurological signs, and there is no obvious organic or functional lesion related to the onset of the disease by various examinations. 2. Pain characteristics 1. no aura symptoms before the onset of pain, sudden onset, rapid cessation, intervals completely normal, most patients have increasingly frequent attacks, there can also be weeks to years of remission, but there are few self-healing, 2. the site of pain is strictly limited to the frontal or facial distribution of one or several branches of the trigeminal nerve, the right side is more, accounting for about 60%, absolutely will not string to the opposite side, but less than 5% of the bilateral The pain is mostly centered on the second branch, the second branch alone and the second branch involved account for about 25%, the second and third branches at the same time, accounting for about 32% to 42%, followed by the second or third branch, the first branch disease does not exceed 5%, 3, the nature of pain is lightning, superficial and sharp sharp pain, often described as knife-like, electric burning, fire-like or tearing pain, 4, the degree of pain is extremely The pain is extremely severe, and the expression of pain is abnormally painful when the pain attacks, as shown by: rubbing the face with hands, so that the skin is swollen and broken, and the eyebrows and beard are rubbed out; some cry out frequently; some hit their heads violently against the wall or roll on the ground; some patients are dazed, seemingly shocked by some unexpected blow, and maintain their original posture, not daring to move; 5. In about 1/3 of patients, a certain area of the facial trigeminal nerve distribution is particularly sensitive, and the slightest touch can cause a painful attack, which is called the “trigger point” or “trigger point”, and the trigger point is often located in the area dominated by the painful branch, such as the lips, paranasal area, gums and tongue. The above is some basic knowledge about trigeminal neuralgia, I hope it will help trigeminal neuralgia patients, if they suffer from trigeminal neuralgia, they should promptly carry out some regular symptomatic treatment to prevent the condition from worsening and causing some more severe pain.
