Dangerous Low Back Pain
It is said that many of low back pains are caused by stiffness or scars of the muscles, but there is a dangerous low back pain caused by the compression of the nerve in the low back, which is a herniated (intervertebral) disc.
A herniated disc is the condition that the disc between bones in the low back, which called Intervertebral disc, bulges out and stimulates the nerve, causing low back pain or numbness in the leg (Fig. 1).
How to check whether your low back pain is caused by a herniated disc or not
(1) Stand with your feet shoulder-width apart (Fig. 2).
(2) Stand on tiptoe for 10 seconds.
If you stagger or your heels touch the ground within 10 seconds, you may have a herniated disc.
When the nerve from the back to the leg is disturbed by a herniated disc, the calf doesn’t have strength or feels numb, making difficult to stand on tiptoe stably.
Exercise to prevent a herniated disc
(1) Sit straight on a chair (Fig. 3).
(2) Bend your upper body forward slowly to more than 45 degrees and return to the original state (Fig. 4).
(3) Repeat 10 reps.
