The sciatic nerve supplies skin, organs and muscles from the low back to the toes. When pressure is placed along the path of the sciatic nerve, it causes a condition called Sciatica (irritation of the sciatic nerve). Common reasons for pain and irritation can include physical stress such as falls, bending down and twisting or pressure due to pregnancy, improper posture or from disc damage between the spinal bones.
Sciatic pain can vary from infrequent and irritating to constant and incapacitating. Specific sciatica symptoms can be different in location and severity, depending upon the condition causing the sciatica.
