Is this really sciatic neuralgia?

At first I wonder if it is not sciatic neuralgia to doubt if I feel a pain and numbness to buttocks and lower limbs.
The sciatic neuralgia has the transformation of the intervertebral disk to tie a bone and a bone to because a burden depends on a waist and says that a pain and numbness appear by pressing the nervous system controlling the function of lower limbs called the sciatic nerve.
Then I will think about a conceivable cause from the symptom that ourselves can notice concretely.
In the case of sciatic neuralgia, it is very likely that the cause "is "a herniated intervertebral disk" or hips spinal canal stenosis".
A body protrudes backward, and, with "the herniated intervertebral disk", an intervertebral disk is a disease to suppress nerve and says the disease that the way of the nervous system called a vertebral canal gets narrow with "the hips spinal canal stenosis", and presses the nervous system.
It is the latter that ache when it bends it in the former behind that pains increase when they defeat it in front of a body for plain distinction.
But a pain comes out when it accompanies both even if I defeat it in whichever.
However, I am dangerous at all because this is an aim to suppose the cause of slight sciatic neuralgia when I treat it by own way by the self-judgment that watched only this symptom.
It may be said that it is wise that the last judgment entrusts a specialist of the orthopedics after having supposed the possibility of the cause by oneself.
