Introduction
Left arm pain may be caused by physiological reasons or pathological factors such as periarthritis of the shoulder or cervical spondylosis. Severe cases may require surgical treatment. In addition, coronary heart disease can also cause left shoulder pain. Patients are advised to seek timely medical attention, identify the underlying cause under a doctor's guidance, and receive appropriate treatment. Self-diagnosis should be avoided to prevent worsening of the condition.
Left arm pain may be caused by physiological reasons, or it could result from pathological factors such as shoulder periarthritis (frozen shoulder) or cervical spondylosis.
1. Physiological Causes
If one consistently sleeps on their side or applies prolonged pressure on the left shoulder and arm, pain may develop. Similarly, engaging in strenuous activities such as playing basketball or bowling can also lead to pain in the left shoulder and arm. In such cases, symptoms usually resolve spontaneously.
2. Pathological Factors
2.1 Shoulder Periarthritis
As shoulder periarthritis progresses, the pain may radiate to other areas. When the pain radiates down the arm, it can cause discomfort in the left arm. Under a doctor's guidance, comprehensive treatments such as local trigger point injections, massage, and manipulation may be used to relieve symptoms.
2.2 Cervical Spondylosis
Cervical spine disorders may damage the spinal cord, nerves, or blood vessels. The nerves supplying the arms originate primarily from the cervical spinal cord. When these cervical nerves are compressed, the brachial plexus may also become involved, leading to neuropathic pain in the left arm. During periods of mild left shoulder pain, physical therapies such as heat application may be beneficial. During acute episodes, medications such as ibuprofen capsules or celecoxib tablets may be taken orally under medical supervision. In severe cases, surgical intervention may be required.
In addition, coronary heart disease may also cause pain in the left shoulder. Patients are advised to seek timely medical evaluation to determine the underlying cause and receive appropriate treatment under professional guidance. Self-diagnosis should be avoided to prevent delays or complications in managing the condition.
