Symptoms and clinical manifestations of peripheral neuritis include these

Factors causing peripheral neuritis include heavy metal poisoning, nutritional metabolic disorders, infection, etc. The main symptoms are movement and nerve function disorders, especially in the lower limbs. Prevention and treatment are necessary to strengthen your physical fitness.

1. Symptoms of peripheral neuritis

The main clinical manifestations are symmetrical sensory, motor and autonomic dysfunction mainly in the distal limbs, and are often more severe in the lower limbs. In the early stages of sensory impairment, symptoms include burning, pain, numbness, or other paresthesias at the fingertips (or toes), or hyperesthesias, which gradually lead to decreased or even disappearance of sensations. The distribution of sensory disturbances is glove- or stocking-like.

A small number of patients may have deep sensory impairment. There is often tenderness in the gastrocnemius muscle and other places. Movement disorders are manifested as decreased muscle strength, low muscle tone, weakened or absent tendon reflexes. In some cases (such as furazolidone), reflexes may be active. Muscle atrophy may occur after long-term illness. Autonomic dysfunction causes cool, pale, flushed or slightly cyanotic skin on the extremities, less or more sweating, thinning, tender or rough skin, loss of normal luster and increased keratinization of the nails, etc. Due to different causes, the symptoms of the above three groups may be different. If it is caused by furazolidone poisoning, arsenic poisoning, etc., the pain is often more severe; if it is caused by diabetes, muscle atrophy is sometimes more obvious. The severity of clinical manifestations varies. Mild cases may only cause pain and numbness in the extremities without sensory loss or movement disorders, while severe cases may also cause limb paralysis. The prognosis is generally good. Recovery usually starts from the distal part of the limb.

II. Treatment

1. Prevention should be the priority, such as strengthening labor protection, preventing metal and pesticide poisoning, and using furan drugs as little as possible (if they are necessary, vitamin B drugs can be taken at the same time).

2. If neurological symptoms and signs are found, the cause should be eliminated as soon as possible, neurotrophic function should be improved, and physical fitness should be strengthened.

3. If it is caused by heavy metals, antidotes can be used, such as sodium dithiosuccinate (0.5-1.0g added to 20ml of water for injection and injected intravenously 1/day), 5-10 times as a course of treatment; if it is caused by nutritional metabolic disorders, the cause of the nutritional disorder should be found and treated accordingly; if it is caused by diabetes, diabetes should be treated at the same time. Drug treatment can use neurotrophic metabolic drugs and vasodilators to promote the recovery of nerve conduction function.
