How Can I Manage Peripheral Neuropathy Pain?

The disease can affect one nerve alone (single peripheral neuropathy), two or more nerves in multiple regions (multiple single peripheral neuropathy), or many nerves (multiple peripheral neuropathy) at the same time. Mainly affected by The damage may be axon (for example, seen in diabetes, Lyme disease, uremia or various poisonings), or myelin or Schwann cells (for example, seen in acute or chronic inflammatory multiple neuropathy, white matter dystrophy) Disease or Guillain-Barre syndrome). Small unmyelinated or myelinated fibers mainly cause loss of temperature and pain; large myelinated fibers cause impairment in movement or proprioception. Some neuropathies (for example, lead poisoning, dapsone poisoning, tick-borne disease, porphyria, Guillain-Barre syndrome) mainly involve motor fibers; others (for example, posterior root neuritis caused by cancer, leprosy , AIDS, diabetes, or chronic vitamin B6 poisoning) mainly affects the posterior root ganglia or sensory fibers and produces sensory symptoms. Occasionally, the cranial nerves can also be affected together (for example, Kyrgyzstan Lambert-Barre syndrome, Lyme disease, diabetes, diphtheria). Mastering specific ways of peripheral nerve damage can help clinicians determine the cause.

Peripheral neuropathy

Peripheral neuropathy is a syndrome formed by loss of sensation, muscle weakness and atrophy, decreased tendon reflexes, and vascular motor symptoms, alone or in any combination.

Introduction to peripheral neuropathy

Etiology of peripheral neuropathy

The most common cause of damage to a single nerve is trauma. Severe muscle activity or overstretching of joints can cause focal neuropathy, repetitive small injuries (for example, holding small tools often, or air hammer) Excessive vibration shock) can also produce focal neuropathy. Compression or entrapment paralysis usually affects superficial nerves (such as the ulnar nerve, radial nerve, and fibula nerve) and occurs at the osteoid process (For example, in lean or cachexia people and often when alcoholics are asleep or during anesthesia), or in narrow ducts (such as carpal tunnel syndrome). Compression paralysis can also be caused by tumors, bones Hyperplasia, plaster fixation, crutches, or long periods of restrained posture (such as gardening labor), etc. Intranerve hemorrhage, cold or radiation can cause neuropathy. Direct tumor invasion can also produce a single surrounding Neuropathy.

Multiple single neuropathies are usually secondary to collagen-vascular diseases (such as nodular polyarteritis, systemic lupus erythematosus, Sjogren's syndrome, rheumatoid arthritis), sarcomatoid disease, and metabolic diseases ( Such as diabetes, amyloidosis), or infectious diseases (such as Lyme disease, AIDS). Microorganisms can directly invade nerves and cause multiple single neuropathy (such as leprosy).

Polyneuropathy caused by acute febrile disease may be caused by a toxin (such as diphtheria) or by an autoimmune response (such as Guillain-Barre syndrome); polyneuropathy that sometimes occurs after immunization It may also be autoimmune.

Toxic substances generally cause multiple neuropathy, but sometimes they can also cause single neuropathy. They include turpentine, cyclohexyl barbiturate, barbiturate, chlorobutanol, sulfonamides, phenytoin sodium, furantoin , Vinblastine, heavy metals, carbon monoxide, tri-o-cresyl phosphate, phosphorodinitrophenol, many solvents, other industrial toxic substances, and certain AIDS drugs (such as zazitabine, didanoxine).

Nutritional deficiencies and metabolic diseases can cause multiple neuropathy. B vitamin deficiencies are common causes (such as seen in alcoholism, beriberi, malignant anemia, isoniazid vitamin B6 deficiency, malabsorption syndrome, and vomiting in pregnancy) Polyneuropathy can also be seen in hypothyroidism, porphyria, sarcoidosis, amyloidosis and uremia. Diabetes can cause sensorimotor distal polyneuropathy (most common), multiple single nerve Lesions and focal single neuropathy (such as involvement of the oculomotor or abductor nerve).

Multiple neuropathy caused by malignant tumors may be secondary to monoclonal gamma globulinopathy (multiple myeloma, lymphoma), or amyloid invasion into the nerve, or nutritional deficiencies, or as a manifestation of paracancerous syndrome.

Peripheral neuropathy

Wallerian degeneration, axonal degeneration, neuron degeneration, segmental demyelination

Peripheral neuropathy Wallerian degeneration

Refers to a series of changes in the distal nerve fibers after the nerve fibers are broken by various trauma. The axon on the distal end of the stump can only survive for a few days because it does not receive the nutritional support of the soma, and it will soon degenerate and disintegrate. The debris was cleared by phagocytosis of Schwann cells and macrophages. The axons and myelin sheaths on the proximal end of the stump can have the same changes, but stop after only 1-2 Langfei knots are destroyed.

Peripheral neuropathy axis mutation

Poisoning or dystrophy, axonal degeneration, and secondary demyelinating all develop from the distal to the proximal (dying back).

Peripheral neuropathy neuron degeneration

The axon and myelin sheath secondary to neuron cell body degeneration and necrosis is called neuronopathy.

Peripheral neuropathy segmental demyelinating

The myelin sheath is destroyed and the axon remains relatively intact. Pathologically, the peripheral and proximal nerves were irregularly segmented and demyelinated, and Schwann cells proliferated and engulfed myelin fragments.

Peripheral neuropathy complications

Nutritional deficiencies and metabolic diseases can cause multiple neuropathy. B vitamin deficiencies are common causes (such as seen in alcoholism, beriberi, malignant anemia, isoniazid vitamin B6 deficiency, malabsorption syndrome, and vomiting in pregnancy) Polyneuropathy can also be seen in hypothyroidism, porphyria, sarcoidosis, amyloidosis, and uremia. Diabetes can cause sensorimotor distal polyneuropathy (most common), multiple single nerves Lesions and focal single neuropathy (such as involvement of the oculomotor or abductor nerve).

Clinical manifestations of peripheral neuropathy

In clinical peripheral neuropathy, the most commonly involved are the femoral, sciatic, median, radial, ulnar, sural, and lateral femoral cutaneous nerves. Early symptoms are mainly sensory disorders, but electrophysiological examinations often involve motor and sensory nerves. Clinical symmetry pain and paresthesia, lower limb symptoms are more common than upper limbs. There are abnormal numbness, ant walking, insect crawling, fever, and electric shock, and they often reach the knee from the distal toe, and the patient has socks and gloves. Patients with severe sensory disorders may develop arthropathy and ulcers in the lower extremities. The pain was stinging, burning, and drilling pain. It seemed to be painful in the deep part of the bone marrow. Sometimes the pain was severe, such as amputation. Sometimes there are tactile allergies, and even the pressure of the quilt cannot be tolerated. The quilt must be supported. When the motor nerves are tired in time, muscle strength often decreases to varying degrees, and in the later stage, there is dystrophic muscular atrophy. Peripheral neuropathy can be bilateral, unilateral, symmetrical, or asymmetric, but bilateral symmetry is more common.

In terms of physical signs of peripheral neuropathy: Achilles tendon reflexes, knee tendon reflexes are weakened or disappeared; Vibration sensation is weakened or disappeared; Position sensation is weakened or disappeared, especially deep sensation decline.

Treatment and experimental examination of peripheral neuropathy

Western medicine treatment of peripheral neuropathy

Etiology treatment: Those who cause poisoning should immediately prevent the poison from entering the human body and escape from the poisoning environment and toxic substances. Those who are caused by drugs should, in principle, stop taking them as soon as possible. In short, measures should be taken to remove the cause.

General treatment: bed rest in the acute phase should be used for polyneuritis caused by various reasons, large doses of B vitamins, vitB1, B6, B12, severe cases using ATP, coenzyme A. Those with obvious pain use analgesics and sedatives, such as carbamazepine. Adrenocortical hormones such as prednisone, dexamethasone, or hydrocortisone can be used for inflammatory demyelinating lesions. Can also use the vasodilator niacin (50-100mg / time), 5-10mg / dipazol.

Enhance nursing: Keep your limbs functional and turn over frequently to prevent bedsores and lung infections.

Recovery period: functional exercise, acupuncture, massage, physical therapy.

TCM treatment of peripheral neuropathy

Peripheral neuritis belongs to the category of "pulse paralysis" in Chinese medicine.

Pulse paralysis is characterized by insufficient righteousness, mixed with six kinky, invading blood veins, causing blood clots, and obstruction of the blood vessels. The main characteristics are limb pain, irritable skin, dark or pale skin, weak pulse or no pulse. A kind of disease certificate. The disease can occur all year round, but it is more common in summer due to damp and hot, and it is more common in winter due to cold or dampness or yang deficiency. The age of onset is mostly young, followed by old age, and young usually does not have the disease, and the difference is small.

Mai Bi was first seen in the "Inner Canon of the Yellow Emperor". Later, medical records such as "Golden Chronicles" have records of blood paralysis. Blood gas obstruction is related to meridian obstruction, so blood obstruction is similar to pulse obstruction. Although later generations of medical books deal with those who suffer from pulse paralysis, they are not officially listed as a disease type, and they lack a systematic discussion on the etiology, pathogenesis, and dialectical treatment. From clinical practice, it is not uncommon for Mai Bi to be a disease, so it is listed as one of the diseases. Those with blood stasis as the main disease syndrome should belong to this disease.
