After the unilateral lumbar muscle strain, you should also actively improve the examination to clarify the specific degree of injury and clarify whether there is a transverse process fracture, in most cases, conservative treatment will be able to get a good recovery, but must pay enough attention, otherwise it is easy to lead to lumbar muscle strain, and later there may be frequent muscle strains. It is best to sleep on a hard bed for 3-4 weeks to allow the injured soft tissues to recover adequately, strengthen warmth, avoid getting cold, and do not push and massage. Intermittent cold compresses can be applied within 2 days of the injury to help reduce bleeding, eliminate swelling and relieve pain. After 2 days of injury, apply hot compresses locally to promote the elimination of swelling and the supply of nutrients to facilitate the recovery of injured tissues. After 3-4 weeks, you can gradually get out of bed and walk under the fixation of the lumbar girth, gradually, avoiding excess, and take off the lumbar girth when resting in bed.
