How long do I have to lie down after a back reset to get better? This situation needs to be based on the specific reason for the reset. If a compression fracture of the lumbar spine occurs, it is generally necessary to be strictly bedridden for about 4 weeks after the reset, and to take a review after 4 weeks to see if the fracture end of the compression fracture has achieved clinical preliminary healing and whether the fracture line is blurred, and then decide whether it is possible to get out of bed; generally it takes about 3 months to achieve complete healing, that is, very solid healing. If the repositioning is due to a disorder of the small joints of the lumbar spine, such as synovial impingement of the synovial joint, bed rest is usually required for 3-5 days after the repositioning, because this time belongs to the edema period, and if activities are performed without bed rest, it may lead to further aggravation of the inflammatory edema, resulting in more obvious pain, so bed rest is chosen. In addition, after the edema period has subsided and the pain has significantly improved, you can get out of bed and generally do not have a significant impact on your activities and do not feel any significant pain.
