As a disc degenerates, it can herniate back into the spinal canal, which is known as a disc herniation (or a herniated disc). The nerve is under pressure by a herniated disc that can cause pain to radiate all the way down the leg to the foot.
And basically there is low back pain in most cases.

important : You must identify well the exact area of radiating pain. If the radiating
pain exist from the buttock to the knee level, then, your pain is due
to muscular origin not by disc herniation. In this case, you need Analgia.
If the radiating pain is from the buttock to the foot, then, you may be suffering from disc herniation.
