The main causes of shoulder pain include shoulder and back muscle strain, excessive exercise, cervical spondylosis and joint diseases.
1. Shoulder and back muscle strain: after a long time of lack of exercise, sudden strenuous exercise or improper exertion can easily lead to muscle strain, thus causing shoulder and back muscle strain, which further causes local inflammation and exudation, resulting in the symptoms of shoulder aches and pains. In addition, long-term head down or poor posture, is also one of the reasons.
2. Excessive exercise: In the large intensity of exercise, especially activities involving the shoulder joint, will be localized in the shoulder accumulation of lactic acid or damage to the rotator cuff, causing the symptoms of shoulder pain. Generally it can be relieved after rest.
3. Cervical spondylosis: Cervical spondylosis is a degenerative change of the cervical intervertebral disc, which irritates or compresses the nerve roots, spinal cord and blood vessels in the neck, causing pain in the neck and shoulders. Shoulder pain can radiate to the limbs, mostly accompanied by neck, shoulder and back stiffness, tinnitus, dizziness and other symptoms.
4. Joint diseases: including soft tissue inflammation around shoulder joint, frozen shoulder, rheumatoid arthritis, tendonitis. When suffering from frozen shoulder, aseptic exudates appear at the shoulder joint, leading to adhesion of the surrounding ligaments and soft tissues, causing shoulder joint movement disorder and pain at the shoulder blade. Rheumatoid arthritis is caused by hemolytic streptococcal infection. Tendonitis is mostly related to long-term strain.
Based on the symptoms of shoulder pain alone can not accurately determine the cause, but also need to be combined with the characteristics of the medical history, other test results to make an accurate judgment, it is recommended to clarify the cause of the disease under the guidance of a doctor.
