Lumbar sprain is commonly known as "waist flash". Most people often bend down to lift heavy objects, so we hope you will avoid such movements. The focus of first aid is to rest in a comfortable position and apply cold compresses.

Lumbar sprain is caused by the sudden pulling of the waist muscles when bending down to pick up heavy objects.

When you suffer a lumbar sprain, you must first maintain a comfortable posture and rest quietly. At this time, you can bend down on the bed, but do not lie on a mattress that is too soft.

Lying on your back with your feet straight should be avoided. This not only increases pain, but may also cause numbness in the feet.

Cold compresses can relieve pain. So you might as well use a wet towel to apply cold compress to your waist.

Slight waist flashing can be cured automatically as long as you rest for 1-2 days. However, if the pain persists or becomes more and more painful, you need to seek medical attention (orthopedic surgery) as soon as possible.

In addition, not only muscle pain, but also intervertebral disc herniation may cause low back pain, so you should go to the hospital for examination when you have low back pain.

When going to the hospital, try not to let the injured person move around.

It is best to keep the injured person in the most comfortable position and take him to the hospital in a car
