LET US LEARN ABOUT SCIATICA
Sciatica is a common problem that accounts for most of the visits to the hospital. This problem is confusing and many people find it difficult to understand, especially how its symptoms happen along with waist pain. This short article will provide a more detailed information on most important areas of sciatica to broaden peoples’ understanding.
Sciatica is a problem with the sciatic nerve. The sciatic nerve is the largest nerve in the body. It starts at the lower lumbar segment (L4) and ends at the third sacral vertebrae (S3) and goes through the pelvis and deep muscles including the piriformis muscle - the muscle that starts in the front part of the pelvic bone and extends to the buttocks - the glutes area and hip areas.
The sciatic nerve passes through and stimulates movement of the biceps femoris, semitendinosus, and semimembranosus muscles. These three muscles or their associated tendons - where they attach to bones - are known as the “hamstrings.”
The sciatic nerve also stimulates sensations in the skin of the feet and outer portion of the calf.
Sciatica is a general term that refers to pain in the buttocks that travels to the thigh, past the knee, and may extend to the calf, foot, and toes. It is due to irritation or pressure on the root of the sciatic nerve.
Other medical terms for sciatica include radicular pain, lumbosacral radicular syndrome, nerve root pain, and nerve root entrapment.
Sciatica is usually related to a problem with the spine - the bones, discs, etc. of the back. Regardless of the spinal problem, the radiating leg pain is due to an inflamed or compressed nerve root.
CAUSES:
A herniated disc causing pressure on the sciatic nerve root
Spinal stenosis, the narrowing of the area in which the nerves pass through the spine
Degenerative disc disease, a condition with changes in the spinal discs and bones, that is usually associated with normal aging
A vertebra, one of the
