Frozen shoulder in diabetic patients may be caused by shoulder trauma, prolonged over-activity, and cervical spondylosis. Patients can be relieved by exercise rehabilitation and taking drugs such as diclofenac sodium extended-release tablets. 1. Shoulder trauma: diabetic patients may suffer from frozen shoulder due to trauma of the shoulder joint, which leads to immobilization of the shoulder for too long a time and causes secondary atrophy and adhesion of the shoulder. Scientific exercise rehabilitation should be carried out to gradually increase the mobility of the shoulder joint to relieve it. 2. Long-term over-activity: If the soft tissue of the shoulder joint of diabetic patients degenerates, the bearing capacity of the shoulder joint decreases, and the symptoms of frozen shoulder may appear after long-term repeated activities and weight-bearing, etc. The patient can take diclofenac sodium palliative. Drugs such as diclofenac sodium extended-release tablets and meloxicam tablets can be taken to reduce the symptoms. 3. Cervical spondylosis: If the cervical spine of diabetic patients has degenerative disease, which triggers the joints to be misaligned, may affect the surrounding soft tissues, and muscle adhesion and contracture may occur, which may cause frozen shoulder. Medications such as ibuprofen and diclofenac sodium extended-release tablets can be taken for relief. If diabetic patients have frozen shoulder, they should go to the hospital in time, improve the examination to clarify the cause of the disease, and then carry out the treatment under the guidance of the doctor, and do not use medication privately.
