My Leg Goes Numb When I Sit The sciatic nerve is the largest nerve in your body, approximately the size of your little finger. This nerve is made up of a group of nerves from your low back that combines together, travels through your buttock and down the back of your leg to your foot. It gives you both feeling and strength in your leg. If this nerve is pinched, you can experience mild discomfort progressing to severe pain. Typical symptoms include tingling, numbness, burning, shooting pain, aching and weakness in your leg. Several different conditions can cause sciatica.

Sciatica Pain Causes, Symptoms, and Treatments Sciatica is an inflammation of the sciatic nerve, the longest nerve in the body, which runs from the spinal cord across the buttock and hip area and down the back of each leg. Sciatica is actually a secondary symptom of another problem placing pressure upon the nerve, most often a herniated disk.

Sciatic nerve damage Sciatic nerve damage. The sciatic nerve is located in the back of the leg. It supplies the muscles of the back of the knee and lower leg. The sciatic nerve also provides sensation to the back of the thigh, part of the lower leg, and the sole of the foot. Partial damage to the nerve may demonstrate weakness of knee flexion (bending), weakness of foot movements, difficulty bending the foot inward (inversion), or bending the foot down (plantar flexion). A person's reflexes may be abnormal, with weak or absent ankle-jerk reflex.

Sciatic nerve Sciatic nerve. The sciatic nerve is the dominant nerve that innervates the lower back and the lower extremities. It travels from the lower spine, through the pelvis, and down each leg.It is the longest and widest nerve in the human body.he sciatic nerve branches into different parts of the body along its path, hence its ability to supply such a large area of the body. It is a mixed-function nerve, meaning that it contains both sensory neurons and motor neurons.

SCIATICA What is Sciatic Nerve Pain? Sciatica is an irritation of a nerve root in the lumbar spine that can result in pain, weakness, numbness or tingling that may travel down from the low back to the legs and feet. The spinal cord travels down from the brain to the rest of the body and is encased and protected by the spinal column.

Sciatic nerve The sciatic nerve is formed from the L4 to S3 segments of the sacral plexus, a collection of nerve fibres that emerge from the sacral part of the spinal cord. The fibres unite to form a single nerve in front of the piriformis muscle.

- Sciatica is pain, tingling, or numbness produced by an irritation of the nerve roots that lead to the sciatic nerve. The sciatic nerve is formed by the nerve roots coming out of the spinal cord into the lower back.It goes down through the buttock, then its branches extend down the back of the leg to the ankle and foot.ymptoms of sciatica include pain that begins in your back or buttock and moves down your leg and may move into your foot. Weakness, tingling, or numbness in the leg may also occur. 1  Sitting, standing for a long time, and movements that cause the spine to flex (such as knee-to-chest exercises) may make symptoms worse.

Sciatica Sciatica is a term for pain that radiates along the sciatic nerve, anywhere from the lower back, buttocks, down the back of the leg, to the foot. There may also be weakness, numbness, tingling, particularly in the leg and/or foot. The location of the pain and/or numbness varies according to the location that the sciatic nerve or nerve root is affected. The pain can range from burning to aching and can vary in intensity. The pain may be intermittent or constant. Sciatica usually occurs on only one side of the body.

Overview Sciatic nerve. Sciatica refers to pain that radiates along the path of the sciatic nerve, which branches from your lower back through your hips and buttocks and down each leg. Typically, sciatica affects only one side of your body. Sciatica most commonly occurs when a herniated disk, bone spur on the spine or narrowing of the spine (spinal stenosis) compresses part of the nerve. This causes inflammation, pain and often some numbness in the affected leg.

The Sciatic Nerve The sciatic nerve innervates most of the hind limb. As is the case with many of the large nerves of the vertebrate nervous system, the sciatic nerve is a mixed-function nerve, meaning it is made up of the axons of sensory and motor neurons. The sciatic nerve gives rise to branches as it progresses distally along the hind limb.

Sciatica in Depth Sciatica is a form of 'Radiculopathy' (pain, weakness or altered sensation along the distribution of a nerve) which is usually caused by irritation of a 'nerve root' located in the lower back, although there are other causes of Sciatica.

- True sciatica is a condition that occurs when a herniated disc or osteoarthritic bone spurs compress and pinch one of the contributing roots of the sciatic nerve. This is known as a pinched nerve. This type of lower back pain is less common than other causes and conditions that produce back pain.

Where is the sciatic nerve located in the body? Sciatica is a form of nerve dysfunction that can occur when the sciatic nerve is compressed. Often, the source of the pressure is a degenerative spine condition, such as a herniated disc or bone spur, which causes narrowing of nerve passages and compresses the sciatic nerve. The resulting symptoms, known as sciatica, arise when motor or sensory impulses are unable to pass properly along the length of the nerve. Sciatica can include: Pain
