Peripheral neuritis generally refers to multiple peripheral neuritis, and common complications include nerve paralysis, muscle atrophy, and limb paralysis. Multiple peripheral neuritis is mainly related to poisoning, nutritional disorders, infections and other factors, which can cause patients to develop abnormal sensation in the distal part of the affected limb and symmetrical muscle weakness in the distal part of the limb. If the patient does not pay attention to it and the condition further aggravates, it is easy to induce complications such as nerve paralysis, muscle atrophy, limb paralysis, joint spasm, etc., which affects the patient’s quality of life and health. In order to prevent complications, patients with multiple peripheral neuritis should take vitamin B1, methylcobalamin and other nutritive drugs as prescribed by the doctor, and can also apply gabapentin, pregabalin and other calcium channel modulators to relieve pain. It is recommended that patients with polypoidal peripheral neuritis be treated with medication under the guidance of a doctor, and should not use medication indiscriminately or increase or decrease the dosage of medication on their own. Daily attention should be paid to appropriate massage and hot compresses on the limbs to promote local blood circulation, and some patients should also seek regular medical review to monitor the changes in their conditions.
