First of all, it is necessary to find out whether the low back pain is caused by lumbar muscle injury (cold, strain, strain) or lumbar disc injury. Be sure to go to the hospital to see a doctor for examination and diagnosis, and then determine the treatment plan, so as to fundamentally solve the problem. You can't rely on illness, especially if you are young and your body is still in the stage of growth and development. Don't look at this blindly. If it is a lumbar muscle injury, do some hot compress, massage, or treat it with drugs that relax muscles and tendons, promote blood circulation and diminish inflammation, and it will get better after a while, but you can't do strenuous exercise during the treatment. If there is a problem with the lumbar spine, we must pay attention to it.

It is best not to wear waist protectors at ordinary times. If it is too tight, it will affect blood circulation, but it is not good for the recovery of lumbar muscles. It can be worn during training to play a fixed role and prevent injuries from happening again.
