Introduction
Numbness in the left arm and hand swelling may be caused by factors such as poor posture, cervical spondylosis, or periarthritis of the shoulder. It is important to seek timely medical evaluation and relieve discomfort through general treatments or medications. In addition to these causes, conditions such as carpal tunnel syndrome, diabetes, or cerebral infarction could also be responsible. Prompt hospital visit is necessary to establish an accurate diagnosis and receive targeted treatment.
In general, numbness in the left arm accompanied by hand swelling may be caused by improper posture, cervical spondylosis, periarthritis of the shoulder, and other factors. It is important to seek timely medical evaluation and relieve discomfort through conservative treatments or medications. Specific analyses are as follows:
1. Improper posture
If sleeping posture is incorrect or if one maintains the same position for prolonged periods during daily activities, long-term compression on the left arm may impair local blood circulation, leading to ischemia and hypoxia in arm muscles and nerves, thereby causing symptoms such as numbness and swelling. Generally, adjusting posture and engaging in appropriate exercise can gradually alleviate these symptoms.
2. Cervical spondylosis
Cervical spondylosis refers to a group of symptoms and signs caused by degenerative changes in the cervical intervertebral discs that irritate or compress cervical nerve roots, spinal cord, or blood vessels. In patients with severe cervical spondylosis, not only neck and shoulder pain but also compression of upper limb nerves may occur, resulting in pain and numbness. Patients should ensure adequate rest and reduce time spent on desk work, bending the head forward, or using mobile phones and computers. Additionally, medications such as ibuprofen sustained-release tablets or celecoxib capsules may be taken under medical guidance.
3. Periarthritis of the shoulder
Periarthritis of the shoulder is a common adhesive inflammation of the joint capsule, possibly caused by excessive activity over a long period or poor posture. Patients may experience pain around the shoulder joint and restricted movement; in severe cases, symptoms such as soreness and swelling in the arm may develop. Treatment may include medications such as loxoprofen capsules or meloxicam capsules, used under a doctor's supervision.
Besides the above-mentioned causes, conditions such as carpal tunnel syndrome, diabetes, or cerebral infarction could also lead to similar symptoms. Timely hospital visits are necessary to establish an accurate diagnosis and receive targeted treatment under medical supervision.
