Causes of Back Pain: Sciatica

Sciatica is a pain disorder that affects the hips, legs, feet, and back, whose main pain generator is in the sciatic nerve or one of the five spinal nerve roots that give rise to the sciatic nerve. A pain generator in medical terms is the anatomical region that is the source of the pain, either due to an injury or degenerative condition. There are many symptoms of sciatica other that pain, including weakness, burning, numbness, and tingling. This condition could range in severity from annoying and uncomfortable to disabling, with a possible loss of functioning of the leg on the affected side.



The sciatic nerve is formed from several spinal nerves that pass through the openings in the sacrum, the lowest portion of the spine. The spinal cord itself terminates in most adults at about the level of L2 in the lumbar spine, but several nerves continue below this point to supply the pelvis, groin, and pelvis. The sciatic nerve extends from the level of the sacrum, which is suspended between the pelvis at the sacroiliac joints, through the legs and all the way into the ends of the feet. The sciatic nerve is the main nerve in our legs, and the longest nerve in the body. There is one sciatic nerve for each leg that extends from each side of the sacrum. The sciatic nerve passes through the sacrum, but actually originates in the lower back. From its point of origin, the sciatic nerve begins in the lower back, and passes through the deep layers of the buttock muscle, to the back of the thigh, and down the leg. The sciatic nerve branches for the first time on the posterior (back) side of the leg, just above the knee. The first of these large branches turns towards the outer edge of the leg and ends just below the patella (kneecap). The second of the two large branches extends down the back of the leg into the heel area.

The sciatic nerve is the longest and one of the most important nerves of the body, due to the amount of structures it supplies with sensory and motor information. If any part of this nerve is compressed or irritated, the patient may experience pain at that location, or at any location away from that side of impaction/irritation where the nerve extends. Other associated symptoms in addition to pain include burning, achiness, weakness, tingling, and numbness. This is sciatica.

Sciatica is a symptom of nerve compression or irritation. sciatica is an inflammatory condition caused by inflammation to the sciatic nerve. The treatment for this condition will depend on the cause and location of the sciatic nerve disruption. Causes of Sciatica: The sciatica nerve can be irritated by a number of conditions. The most common causes of sciatica are emotional stress, a herniated or bulging disc, spinal stenosis, lumbosacral muscle strain, and an inflamed prirformis muscle. Lack of physical conditioning or strength in the back and abdominal muscles may make a person more prone to the symptoms of sciatica. Less common causes of sciatica include sacroiliac ligament tears, ankylosing spondylitis, endometrial cysts, and arthritis.

Treatment of Sciatica: The sciatica treatment appropriate to your condition will depend on the cause of the symptoms, location of the symptoms, and whether your condition has an emotional component. When muscle weakness or strain is involved with causing the symptoms, the person will either perform daily back exercises to strengthen the muscles, or change postural techniques in order to keep these muscles from becoming chronically strained.
