For patients with fever, significantly increased blood sedimentation, and increased white blood cells between acute attacks or recurrent attacks; those with significant swelling of the affected joints and effusion in the joint cavity; those with significant lesions in the cervical spine or weight-bearing joints of the lower limbs; and those with complications of vasculitis or cardiopulmonary lesions. Bed rest for 2-3 weeks is appropriate, and when the acute symptoms or systemic symptoms and arthritis disappear and joint pain is reduced, you can get out of bed and move around. Long-term bed rest can lead to joint stiffness, muscle atrophy, bone atrophy and increased bone fragility. Exercise should be gradual, to the extent that it just triggers pain, warm compresses before exercise, and often change the exercise. Rest at least 10 minutes for every hour of exercise, at least 2 times a day. At the beginning, simple functional exercises such as rehabilitation exercises (attached) can be performed, and later the amount of exercise can be gradually increased to fast walking and backward walking (a proven method that can be easily mastered and adhered to). Patients who are in good health can also do fast running, long-distance running and variable speed running, in addition to traditional Chinese martial arts such as taijiquan, taiji sword, five-animal play, qigong, cycling, elderly disco, traditional dance and aerobics. Each person chooses according to his or her own situation. Exercising in warm water can reduce joint pain and promote muscle relaxation.
