Because most of them are sudden injuries, patients feel local pain is very intense, which is aggravated with local activities and vibration, and can be relieved after lying down. The pain point is fixed and consistent with the position of muscle tearing, especially near the posterior superior iliac spine and the spinous process of thoracolumbar spine, and also at the lateral process next to the vertebral body.
The tenderness point is obviously limited, and sometimes it can radiate from this pain point to the back of the thigh, which will be aggravated with the increase of abdominal pressure. Conductive percussion pain is mostly negative and has no obvious relationship with lower limb elevation (when checking the bed). The pain can be relieved after local sealing.
Causes of frequent hip swing
1. Unprepared activities: Whether it is physical labor or various competitive activities, if you can prepare your spine and limbs from slow to fast and from small to large before the official start, you will not be easily injured (including back sprain). On the contrary, it suddenly began to increase the spinal load without warm-up activities.
2. Improper posture: In daily work, especially on weekdays, workers who rarely have the opportunity to engage in heavy physical or mental work are often not used to the normal steps of moving forward, bending their knees, bending their knees, bending their knees, bending their knees, and then holding the object with both hands, gradually straightening their knees and hips while lifting (lifting), resulting in improper exertion and spraining their backs.
