What are the symptoms of peripheral neuritis

Peripheral neuritis is also a common symptom, which is a kind of nerve damage caused by various reasons. Patients often experience abnormal sensations in the distal parts of their limbs, causing pain and burning sensations. In addition, they may also cause movement disorders, the most common of which is muscle weakness, which leads to weakened reflexes, etc. These have a great impact on human health, especially on movement. Let’s learn about this aspect.

What are the symptoms of peripheral neuritis

It manifests as symmetrical sensory, motor and autonomic dysfunction in the distal limbs, so it is also called polyneuritis or multiple peripheral neuritis. The onset of this disease can be acute or slow due to different causes. 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.

1. Sensory disturbance: In the early stage, it is often manifested by abnormal sensations such as burning, pain, numbness, or hyperesthesia at the finger (or toe) tips, and gradually the sensation decreases or even disappears. 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.

2. Movement disorders: manifested as decreased muscle strength, low muscle tone, weakened or disappeared tendon reflexes, and reflexes caused by some causes (such as furazolidone).

The following are some common causes

1. Poisoning: such as heavy metals such as lead, arsenic, mercury, phosphorus, drugs such as furacillins, isoniazid, streptomycin, phenytoin sodium, carbamazepine, vincristine, and organic compounds such as organophosphorus pesticides. 2. Nutritional metabolic disorders: such as vitamin B deficiency, diabetes, uremia, chronic gastrointestinal diseases, pregnancy, etc. 3. Infection: It is often accompanied or secondary to various acute and chronic infections, such as dysentery, tuberculosis, infectious hepatitis, typhoid fever, mumps, etc. In a few cases, it may be caused by direct invasion of peripheral nerves by pathogens, such as leprosy neuritis.
