Fibula nerve paralysis

You feel numbness to the instep, and it is assumed that the sense of the foot became funny.
At first what will the conceivable ill cause be?
I hear it with the numbness of the foot, and there may be the person who hits when it is the symptom of the sciatic neuralgia.
However, it is not sciatic neuralgia, and the abnormality may be a disease called the fibula nerve paralysis in the sense of the foot if not accompanied with a pain at all though I feel it.
With the fibula, I play the rib supporting the shin, an ankle from a knee.
And the fibula nervous system is the nervous system in the back and I put up an ankle and a toe and control the cutaneous sensation of lower limbs, but a symptom to feel sense of incongruity appears to a foot does not go up when this fibula nervous system is fixed for various causes, and the nervous system is pressed, aching though there is not it.
If it is a light symptom, I review everyday life and can be improved, but can operate on it to remove pressure depending on a case.
It may be necessary for the person with the idea to think about this ill possibility in such a thing stumbling immediately recently without the sense of the foot is funny, and the foot going up properly.
