Why Does My Arm Feel Tired?

Have you ever experienced a sudden feeling of fatigue or heaviness in your arm that seems to come out of nowhere? If so, you may be wondering why your arm feels tired and what could be causing this sensation. There are several potential reasons for arm fatigue, ranging from simple overuse to underlying medical conditions. In this article, we will explore some of the common causes of arm tiredness and provide valuable insights to help you understand this perplexing issue.

1. Overuse or Muscle Fatigue: One of the most common reasons for arm tiredness is overuse or muscle fatigue. If you engage in repetitive arm movements or perform strenuous activities for an extended period, your arm muscles can become tired, leading to feelings of weakness and fatigue.

2. Poor Posture: Maintaining poor posture for prolonged periods can put excessive strain on your arm muscles, causing fatigue. Slouching or hunching over a desk or computer can lead to muscle imbalances and fatigue not only in your back but also in your arms.

3. Nerve Compression: Nerve compression, such as from a pinched nerve in your neck or shoulder, can cause arm fatigue. When the nerves are compressed or irritated, they can send signals of weakness and tiredness to your arm muscles.
