Do you know what’s sciatica? According to the experts, sciatica is a term that describes symptoms of pain that begin in the lower back and extend down through the buttock, thigh, and into the lower leg and foot. You should know that these symptoms can occur when a nerve or nerve root is compressed or pinched in the lower back leading to the sensation of pain, numbness, and weakness in the leg.
There are multiple locations where the nerve or nerve root can be pinched. We can easily say that one of the most common causes of sciatica is lumbar disc herniation. Repeated mechanical stress to a spinal disc can cause the outer layers of the disc to tear and allows the inner substance to herniate, or push its way out of its enclosed space.
Lumbar disc herniation occurs most commonly at the weakest point of the disc, which is the area where the nerve root exits from the spinal canal. When a disc herniates in this location, it often directly contacts the nerve root which is exiting through the space, thus activating the nerve and causing the feeling of numbness and pain radiating into the leg.
There are other conditions which can mimic the effects of a lumbar disc herniation:
This is very important for you to remember – all health care professionals agree that conservative care should be performed first and that surgery is a last resort for this issue.

Degenerative disc disease.
Piriformis syndrome, which is a condition in which the piriformis muscle becomes tight and compresses the sciatic nerve as it passes through the gluteal region.This is very important for you to remember – all health care professionals agree that conservative care should be performed first and that surgery is a last resort for this issue.
