Introduction
Arm muscle twitching is usually caused by physiological factors, but may also be due to pathological conditions such as malnutrition or amyotrophic lateral sclerosis (ALS). When patients experience excessive mental stress or fatigue, the arm muscles may remain in an excited state during rest, leading to spasms in the muscle areas and resulting in arm muscle twitching.
Arm muscle twitching is usually caused by physiological factors, but it may also result from pathological conditions such as malnutrition or amyotrophic lateral sclerosis (ALS). A detailed analysis is as follows:
I. Physiological Factors
When patients experience excessive mental stress or physical fatigue, arm muscles may remain in an excited state during rest, leading to muscle spasms and twitching. In such cases, there is generally no need for concern. Symptoms can be relieved through adequate rest and proper massage.
II. Pathological Factors
1. Malnutrition
If daily dietary intake lacks sufficient nutrients, the body may become deficient in essential trace elements. This can damage nerve endings, impair blood circulation, and lead to abnormal muscle contractions, resulting in muscle twitching. It is recommended that patients maintain a balanced diet. For more severe cases, medications such as iron dextran oral solution or zinc gluconate tablets may be used under medical supervision.
2. Amyotrophic Lateral Sclerosis (ALS)
This condition is often caused by infections or nutritional disorders that damage motor neurons, leading to arm muscle twitching. Patients may also experience muscle weakness and atrophy. Treatment may include medications such as riluzole capsules or edaravone injection, used under a physician's guidance.
Besides the above causes, poliomyelitis may also lead to arm muscle twitching. If the underlying cause is unclear, patients should seek timely medical evaluation and further diagnosis at a hospital.
