The sciatic nerve is the largest nerve in the body. Inflammation of irritation of sciatic nerve is called sciatica which has an acute painful and burning sensation. Some patients might feel simple numbness or a dull pain.
The sciatica pain is felt from the lumbar region of the vertebral column to behind the thigh and very often it is felt up to way below the knee. Some patients complain of pain all the way up to the upper neck.
Sciatica pain may be acute enough to make even walking very difficult for the person suffering from it. Bending the body at the waist in any direction seems to increase the pain. It can be acutely felt right after standing or sitting.
Common causes of sciatica include:
1. Injury in the hip/pelvic region
2. Herniation of a disc in the vertebral column is a common reason for sciatica inflammation.
3. Pinching or compression of the sciatic nerve due to other bones , tumors or hurt around the area of the sciatic nerve.
Sciatica therefore results from another underlying condition as a symptom.
