Lower back pain after deep squatting is mostly caused by muscle strain, which can be treated by sleeping on a hard board bed to rest, reducing the amount of deep squatting, pasting or applying creams that invigorate blood circulation and remove blood stasis, as well as going to the acupuncture department or Tui Na department.
Sleeping on a hard bed means resting flat on a relatively hard mattress, and at the same time, you can put a small pillow on your lower back to keep your lower back hyperextended and maintain the normal physiological curve of your lower back. At the same time, reduce the amount of exercise, and wait until the low back pain is relieved before performing deep squats. You can also apply ointment with blood circulation and blood stasis externally to the painful area of the waist, or use safflower oil to push and rub.
You can also go to the acupuncture department or Tui Na department for formal Chinese medicine treatment.
If the symptoms persist without relief, it is recommended to seek medical attention.
