Rheumatic polymyalgia is a disease that occurs in the elderly and can be sudden or insidious, manifesting as pain and stiffness in the proximal muscles (scapularis and pelvic girdle) and neck muscles. There may be symptoms such as hypothermia, malaise and weight loss over a period of weeks or months, and the examination shows increased sedimentation and unexplained moderate anemia. It is generally a benign process and is closely related to age, with an increasing incidence with age, and few people suffer from the disease before the age of 50. It is 2-3 times more common in women than in men. In elderly people with unexplained fever and difficulty in raising arms, dressing, squatting and standing up, rheumatic polymyalgia should be considered after excluding other diseases such as tumor. Patients with initial or mild disease can be treated with NSAIDs, such as mobic acid and diclofenac. About 10-20% of patients with rheumatic polymyalgia can control their symptoms with NSAIDs alone. For more severe patients, glucocorticoid therapy can be given, and prednisone tablets 5mg three times a day are generally preferred orally. If the diagnosis is correct, the symptoms should improve significantly within a week and the blood sedimentation should begin to decrease. As the symptoms improve and the blood sedimentation is close to normal, then the dosage should be gradually reduced and the maintenance amount should be 5~10mg per day, and the maintenance time should not be less than 6~12 months. Reducing the dosage too early, too fast or stopping the drug too early can lead to rekindling or relapse of the disease. Most patients can stop using hormone within 2 years, and a few patients need to maintain small amount for many years. With proper treatment, the disease can be rapidly controlled, remitted or cured; it can also be prolonged or recurring; serious conditions such as muscle wasting atrophy or shoulder capsule contracture can occur in the later stages of the disease.
