Left arm pain may be caused by physiological factors such as overexertion, or it may be caused by pathologic factors such as humeral epicondylitis, cervical spondylosis and frozen shoulder.
1. Physiological factors: due to the left arm for a long time exertion caused by local muscle overwork, resulting in the body produces too many metabolites, lactic acid accumulation, resulting in local pain, is a normal physiological phenomenon, appropriate rest can be relieved.
2. Epicondylitis of humerus: due to frequent external rotation of the left hand or manual labor, causing aseptic inflammation of the local soft tissues, which can lead to epicondylitis of the humerus, and pain in the elbow joint and arm muscles.
3. Cervical spondylosis: caused by cervical degenerative disease, chronic strain injury of cervical spine, etc., the patient will have herniated intervertebral discs, osteophytes and other changes, which will cause radiating pain in the left arm when the spinal cord and nerve roots are compressed.
4. Frozen shoulder: it refers to the shoulder joint capsule, ligaments and other tissues, under the influence of chronic strain, trauma and other factors, aseptic inflammation occurs, resulting in pain around the shoulder, and at the same time, the pain can be radiated to the arm, so it will also cause pain in the left arm.
The causes of left arm pain are more, if the pain persists without relief or accompanied by other uncomfortable symptoms, it is recommended that the patient go to the hospital for further examination in a timely manner, to clarify the cause of the disease after targeted treatment, so as not to delay the condition.
