If the shoulder joint is sore and stiff, it is important to consider whether there has been any trauma, or if there is no history of trauma, it may be a symptom of frozen shoulder. Frozen shoulder, also known as frozen shoulder and fifty shoulder, is a chronic strain on the shoulder joint that causes a sterile inflammatory reaction in the tendons, ligaments, and joint capsule of the shoulder joint, resulting in pain and limited movement of the shoulder joint. This condition is common in middle-aged and older women, and because it is a self-limiting disease, it can heal on its own, but it may take 0.5-3 years. Physical therapy, rest, and appropriate functional exercises are recommended after the appearance of frozen shoulder, and symptomatic treatment with non-steroidal anti-inflammatory and pain-relieving drugs can be applied if necessary. If there is a history of trauma, it may be an injury to the tendons, ligaments or articular cartilage of the shoulder joint, so it is recommended to visit the orthopedic department of a regular hospital.
