Lumbar joint repositioning is for synovial impingement of the lumbar synovial joint, in which the synovial joint squeezes the synovial membrane, which causes severe pain in the lumbar region. The pain can be relieved immediately after the joint is rotated and repositioned, but it takes 3-5 days to fully recover. This is because the synovial membrane of the joint becomes inflamed and edematous after the synovial impaction is formed. Although the impaction has been lifted, the local inflammatory edema still exists and it takes about 3-5 days for the inflammatory edema to be metabolized and absorbed, so that the painful symptoms can disappear completely. In addition, during the 3-5 days of treatment, we must pay attention to the relaxation of the lumbar region, try to choose bed rest, avoid prolonged standing, prolonged sitting, and bending and lifting heavy objects and other actions. At the same time, you should pay attention to the warmth of the lumbar region, not to appear cold, you can use a warm water bag for hot compresses to promote the metabolism of inflammation. In addition, oral anti-inflammatory and pain-relieving drugs can be taken to relieve the symptoms.
