Bladder pain refers to shoulder joint pain, and its may be the precursor of muscle strain, frozen shoulder, cervical spondylosis and other diseases.
1. Muscle strain: long-term gravitational labor with the shoulder will cause damage to the soft tissues around the shoulder joint, and at the same time, the exercise will produce a large amount of lactic acid accumulation in the shoulder joint, resulting in shoulder joint pain and activity limitation.
2. Frozen shoulder: due to pulling or cold stimulation, the shoulder joint produces aseptic inflammation such as oozing and edema, or soft tissue degeneration and spasm, which causes shoulder pain.
3. Cervical spondylosis: changes in the structure of the cervical intervertebral discs may cause the nucleus pulposus to protrude into the annulus fibrosus, which squeezes the spinal nerve roots and blood vessels, slowing down the flow of blood and generating radiating pain, which then radiates to the shoulders and necks, resulting in shoulder pain.
In addition to the above reasons, there are heart diseases, such as myocardial infarction or angina pectoris; respiratory diseases, such as pneumonia, tuberculosis or pleurisy; digestive diseases, such as biliary colic, duodenum can cause bladder pain, so patients with shoulder pain, should be timely to the orthopaedic department of the hospital for treatment.
