肌肉抽搐是不是病

Whether it's an annoying twitch in your eyelid, or a sudden, jarring jerk of the legs when falling asleep, involuntary muscle movements can be, at best, annoying or, at worst, a real cause for concern.

无论是眼睑的烦人抽搐，还是入睡时突然的腿部不适抽搐，无意识的肌肉运动充其量只是烦人，最糟糕的，是真正令人担忧的原因。

The good news is that muscle twitches are a very common occurrence that most people experience at one time or another, and, in most cases, they are nothing to worry about. Dr. Charles Kim, assistant professor of rehabilitation medicine and anesthesiology and a pain management specialist at Rusk Rehabilitation at NYU Langone Health in New York City, told US News & World Report, "For the vast, vast majority of people, [muscle twitching] is benign."

好消息是，肌肉抽搐是大多数人在某个时候都会经历的一种非常常见的现象，在大多数情况下，它们没有什么可担心的。纽约市纽约大学朗根健康中心Rusk康复中心的康复医学和麻醉学助理教授、疼痛管理专家Charles Kim博士告诉《美国新闻与世界报道》，“对绝大多数人来说，[肌肉抽搐]是良性的。”

Muscles are made up of fibers that are controlled by nerves. When the nerves misfire — that is, transmit impulses at unexpected times — a group of muscle fibers may suddenly contract, causing a twitch or jerking movement (via Verywell Health).

肌肉是由神经控制的纤维组成的。当神经失灵时——也就是在意想不到的时候传递脉冲——一组肌肉纤维可能会突然收缩，导致抽搐或抽搐运动。

Usually, muscle twitching is caused by an imbalance in the body due to lifestyle factors. Strenuous physical activity or exhaustion, stress or anxiety, nutrient deficiencies, electrolyte imbalance, and dehydration are just some of the sources of muscle twitching, and doctors will usually ask about these conditions first, per Verywell Health.

通常，肌肉抽搐是由生活方式因素导致的身体不平衡引起的。剧烈的体力活动或精疲力竭、压力或焦虑、营养不足、电解质失衡和脱水只是肌肉抽搐的部分来源，医生通常会根据健康状况首先询问这些情况。

"Oftentimes, the muscle twitching is a sign there's some sort of imbalance going on in your life," Dr. Charles Kim said. "I think the most important thing is just looking at your lifestyle and (seeing) what sort of things may be contributing to it." If your diet is lacking nutrients, you're overworked, or you are not moving your body enough or getting enough rest, according to Dr. Kim, it's beneficial to find ways — like regular exercise and meditation — to improve those factors. "It's achieving a balance." (via US News & World Report).

查尔斯·金博士说：“通常情况下，肌肉抽搐是你生活中出现某种不平衡的迹象。”。“我认为最重要的是看看你的生活方式，看看是什么原因造成的。”金博士说，如果你的饮食缺乏营养、工作过度、或者你的身体活动不足或休息不足，那么找到一些方法——比如定期锻炼和冥想——来改善这些因素是有益的。“这是在实现一种平衡。”。

If muscle twitching is persistent and doesn't go away in a few days, or if it is combined with other symptoms, like muscle weakness or atrophy, it's important to see your doctor, as it could indicate a more serious problem. A health care provider can order diagnostic tests to see if the twitching might be caused by an underlying condition that requires treatment.

如果肌肉抽搐持续几天没有消失，或者还伴有肌肉无力或萎缩等其他症状，一定要去看医生，因为这可能意味着更严重的问题。医疗保健提供者可以要求进行诊断性测试，以确定抽搐是否可能是由需要治疗的潜在疾病引起的。
