What Are the Most Common Causes of Sharp Arm Pain?

Muscle atrophy refers to striated muscle malnutrition, muscle volume shrinks, muscle fibers become thinner or even disappear. It is clinically similar to amyotrophic lateral sclerosis and progressive spinal muscular atrophy of motor neuron disease, but the prognosis is very different. The age of onset was young, and most of the affected sites were unilateral distal upper limb muscles. The electromyogram showed neurogenic damage, and the course was benign and could be stopped on its own. Atrophy of arm muscles: The arm muscles are atrophied and the fingers are numb.

Cause: If the arm muscle atrophy caused by injury is called traumatic muscular atrophy, its disability rate is very high. The cause of the disease is that the neurological paralysis is not secondary to the dominating muscles due to traumatic hemoedema invading the nerve. Muscle atrophy. Disorders of spinal cord blood circulation, limited atrophy of spinal cord from lower neck to upper chest. Domestic Li Zuohan et al. (1994) reported 22 cases. According to the electromyographic examination, it was thought that the anterior horn cells of the spinal cord, especially those in the lower neck, were most likely to be damaged. In addition, detailed examinations were required at the hospital.

Differential diagnosis of arm muscle atrophy:

I. Acute or subacute muscular atrophy

Generally, neurogenic atrophy occurs at a rate that is related to the speed and extent of nerve damage. The more acute and severe the nerve damage and interruption, the faster and more obvious the muscle atrophy occurs. Muscle atrophy occurs after paralysis during acute onset, and the clinical manifestations are mainly paralysis, such as polio, peripheral neuritis, Guillain-Barre syndrome, and alcoholism. Neuralgia muscle atrophy is manifested as severe pain near the scapula at early stage, followed by decreased muscle tension, paralysis and muscle atrophy near the scapula. A single atrophy may appear in some muscle groups in a mosaic pattern.

2. Progressive distal limb atrophy

It is usually neurogenic muscle atrophy, with the distal limbs as the main part, the upper limbs in the interosseous muscles of the hand, the large and small intermuscular muscles, and the lower limbs in the anterior tibial muscle atrophy. The sides are basically symmetrical and often occur before paralysis, as a single symptom. Common diseases include amyotrophic lateral sclerosis and progressive spinal muscular atrophy of motor neuron disease, weakness of the distal upper limb and muscle atrophy caused by cervical spondylosis. Gastrocnemius is characterized by muscle atrophy at the lower third of the thighs of the lower limbs, accompanied by deep and light sensory disturbances, and sensory ataxia. In addition, syringomyelia, spinal vascular malformations, leprosy, and chronic anterior keratitis can cause progressive muscle atrophy in the distal limbs. Atrophic myotonia and distal progressive muscular dystrophy of myopathy are also manifested as muscular atrophy of the distal limbs.

3. Progressive proximal muscle atrophy of the extremities

It is often myogenic atrophy, obvious in the proximal extremities and trunk muscles, and often manifests as atrophy and weakness of the scapular and pelvic girdle muscles. Such as cervical muscle weakness, some patients need to support with their hands to raise their heads. The atrophy of the scapular muscles forms the winged scapula. The atrophy of the pelvic girdle muscles forms a specific lsquo; duck step rsquo; gait. Common diseases are progressive muscular dystrophy, polymyositis, diabetic muscular atrophy, and hormonal myopathy.

Wohfart-Rugelberg-Welancter disease is a genetic disease that occurs in young people. It shows muscle atrophy in the proximal extremities and limb bands, and the gastrocnemius muscle is pseudohypertrophic. This disease is sometimes seen with fibrillation and can be induced by neostigmine. No duck step and winged scapula.

Fourth, localized muscular atrophy

Local muscle or muscle group-based atrophy is usually caused by various mononeuritis or injuries. It is usually accompanied by the innervation of the corresponding sensory area disorders. The lesion can be located according to its anatomy. Common causes include single nerves. Inflammation (such as radial nerve, peroneal nerve, sciatic nerve injury, etc.), carpal tunnel syndrome, brachial plexus injury, neurofibromas, etc. Others include:

1. Spinal gray matter softening can be manifested as distal progressive muscular wilt, or confined to the hand, does not invade the forearm and upper arm, and the atrophy stops to a certain extent. It is accompanied by sensory disturbances, occurs in old age, and is often caused by syphilis vascular disease.

2. Youth unilateral upper limb muscle atrophy occurs in 14 to 24 years of age. It is more common in men, and the disease is hidden. It manifests as a thinning below the midpoint of the forearm. Laterally, the atrophy has clear boundaries and no sensory disturbances, but autonomic nerve disorders are more obvious. The disease stops on its own within 1 to 3 years.

3. Reflex muscle atrophy refers to a disuse atrophy of muscles due to local lesions such as joint lesions. Found in traumatic, infectious, rheumatoid arthritis. Rheumatoid arthritis can cause systemic muscle atrophy.

Diagnosis: The arm muscles are atrophied and the fingers are numb.

Patients with muscular atrophy stay in bed for a long time due to muscle atrophy and muscle weakness, and are prone to complicated with pneumonia and bedsores. In addition, most patients have symptoms of bulbar palsy, which poses a great threat to patients' lives. In addition to asking a doctor for treatment of muscular atrophy, self-regulation is very important.

1. Stay optimistic and happy.

Stronger long-term or repeated emotional changes such as stress, anxiety, irritability, and pessimism can make the cerebral cortex excite and inhibit the balance of the process of imbalance, increase muscle jumps, and develop muscle atrophy.

2. Reasonably adjust the diet structure.

Patients with muscular atrophy need a high-protein, high-energy dietary supplement that provides the substances necessary for the reconstruction of nerve cells and skeletal muscle cells to enhance muscle strength and muscle growth. Early use of high-protein, vitamin, phospholipid, and trace element-rich foods, and Actively cooperate with medicated diets, such as yam, barley, lotus seed heart, tangerine peel, ginseng, lily, etc., fast food spicy, quit smoking and alcohol.

Patients in the middle and advanced stages are mainly high-protein, high-nutrition, energy-rich semi-liquid and liquid foods, and use less food and more meals to maintain the nutrition and water-electrolyte balance of patients.

3. Combination of work and rest.

Forced sexual function exercise is forbidden, because forced sexual function exercise will cause skeletal muscle fatigue, which is not conducive to the recovery of skeletal muscle function, regeneration and repair of muscle cells.

4. Strictly prevent colds and gastroenteritis.

Patients with muscular atrophy have low autoimmune function or some kind of immunodeficiency. Once the patients with muscular atrophy have a cold, their condition becomes worse and their course prolongs, and their muscle atrophy and muscle jumps become worse. Especially patients with ball paralysis are prone to complicated with lung infection. Prompt prevention and treatment, poor prognosis, and even endanger patients' lives.

5. Gastroenteritis

Gastroenteritis can cause intestinal bacterial dysfunction, especially viral gastroenteritis can damage the anterior horn cells of the spinal cord to varying degrees, which can make muscle atrophy patients with increased muscle jumps, decreased muscle strength, repeated or aggravated conditions. Maintaining normal digestive function in patients with muscular atrophy is the basis of rehabilitation.
