Sciatica symptoms are caused by compression of the sciatic nerve. This nerve is responsible for feeling and movement of various parts of the buttocks and legs. The specific sciatica symptoms will depend on which part of the sciatic nerve is actually affected.
Common Sciatica Symptoms
Because the sciatic nerve is being compressed, common sciatica symptoms can include:
Pain through the buttocks and down one leg to below the knee, occasionally reaching the foot.
More Severe Sciatica Symptoms
If more of the sciatic nerve is compressed, sciatica symptoms can become more severe and include numbness or abnormal sensation in the feet and weakness or clumsiness of the lower leg. In extreme cases, sciatica symptoms can include loss of control of bowel or bladder function.
