Understanding Low Back Pain

Low back pain refers to discomfort, pain, or stiffness localized in the area between the ribcage and the pelvis, commonly known as the lumbar spine.

What is Low Back Pain?

Low back pain is a prevalent and complex condition that affects a large percentage of the population at some point in their lives. It refers to discomfort, pain, or stiffness localized in the area between the ribcage and the pelvis, commonly known as the lumbar spine.


  • Dull, Aching Pain: Persistent discomfort in the lower back.
  • Sharp, Shooting Pain: Pain that radiates down the legs, often indicative of nerve involvement.
  • Stiffness: Reduced flexibility and range of motion in the lower back.
  • Muscle Spasms: Involuntary contractions of the muscles causing pain.

Causes of Low Back Pain

1. Muscle Strain:
Everyday activities or sudden movements can strain the muscles in the lower back, leading to pain and discomfort.

2. Lumbar Disc Herniation:
The discs between the vertebrae can herniate or bulge, causing pressure on nerves and resulting in pain.

3. Degenerative Disc Disease:
The natural aging process can contribute to the breakdown of spinal discs, leading to pain and reduced mobility.

4. Spinal Stenosis:
Narrowing of the spinal canal can put pressure on the nerves, causing pain and discomfort.

5. Scoliosis:
An abnormal curvature of the spine can contribute to pain in the lower back.

6. Trauma or Injury:
Accidents, falls, or trauma to the lower back can result in acute or chronic pain.
