A lumbar vertebrae herniated intervertebral disk

You may be assigned to health with television and a magazine, and it is featured, but there is a thing called "the herniated intervertebral disk" in words therefore to often come out.
You may know it not to mention a person that oneself or an imminent person has suffered from hernia, but may not really understand it too much on earth what kind of disease you say with the hernia for a person without such an experience.
In the first place what kind of disease will this name of disease to usually see and hear well be?
You call a cartilaginous tissue such as a cushion connecting a bone and the bones of the backbone the intervertebral disk.
Because there is this intervertebral disk, we bend one's body and can turn it.
However, this intervertebral disk jumps out of the organization which there is around an intervertebral disk called *irin when you take the desk work of the long time, an unnatural posture including the driving of the car and presses Kiyone God whom there is under the sciatic nerve going along the neighborhood.
And symptoms such as a pain or the numbness are given to the physical part (run to a foot from a waist) that pressed Kiyone God runs.
You ache to lower limbs in this way, and a symptom to feel numbness is called sciatic neuralgia generally.
There may be a lot of one thinking to refer to only a thing of the lumbago when you hear it with a herniated intervertebral disk, but the influence on lower limbs that, actually, a sciatic nerve runs in this way is big.
