After a suspected sprain of the lower back, the first thing to do is to stop the activity and rest quietly. If there is pain that cannot be relieved or even tends to worsen after rest, or other conditions that you cannot judge, you should go to a nearby regular medical facility as soon as possible to avoid delaying the condition.
In addition, others should pay special attention to the process of moving patients with lumbar injuries, trying to keep the patient’s lower back in a fixed position, and if not urgent, wait first and then move the injured person under the guidance of 120 emergency personnel.
