Low Back Pain / Sciatica

Low Back Pain / Sciatica may be treated both medically within our Upstate Neurology clinic and surgically at our Upstate Brain and Spine Center.

Low Back Pain and Sciatica symptoms, treatment and information

Low back pain is an ache or discomfort in the lower part of the back. It may spread into one or both legs. The lower spinal column is made up of small, stacked bones (vertebrae) that surround and protect the spinal cord and nerves. There are also many muscles and ligaments that attach to the spine. They work together to bend and twist the torso.

There are many possible causes for pain, such as:

  • Sprain or strain of muscles or ligaments
  • Herniated disc or ruptured disc—the cushions between the bones of the spine bulge out of place due to aging or trauma.
  • Disc degeneration—caused by arthritis or aging
  • Scoliosis
  • Lumbar spinal stenosis—bony narrowing of the spinal canal in the low back
  • Spondylolysis—stress fracture of part of the bone in the back
  • Spondylolisthesis—slipping of one bone over another, causing stretching or pinching of nerves
  • Fractures due to trauma or osteoporosis
  • Fibromyalgia—a health problem that causes muscle aches and fatigue
  • Ankylosing spondylitis—a disorder that causes spine stiffness and arthritis
  • Rarely, it may be due to:
    • Cancerous or non-cancerous tumors
    • Infections
    • Problems with arteries, such as hardening of the arteries

Sciatica is irritation of the sciatic nerve. It leads to pain that starts in the lower back and spreads to the buttocks and down the back of the thigh. The sciatic nerve is made up of many nerve roots that start from the lower part of the spinal cord. These nerves form a network that lead to individual nerves. These nerve bundles travel deep in the pelvis to the lower buttocks. From there, the nerve passes along the back of each upper leg and divide at the knee into branches that go to the feet.

Anything that causes irritation or puts pressure on the sciatic nerve or the nerves that form it can cause this problem, such as:

  • Herniated disc (ruptured or slipped disc)
  • Disc degeneration
  • Spinal stenosis
  • Spondylolisthesis
  • Piriformis syndrome
  • Rarely, it may be due to:
    • Cancerous or non-cancerous tumors
    • Infections

Low back pain is common. Most back pain gets better with time. Some people will have pain for three months or longer.
