Differential Diagnosis for Lower Left Lumbar Region Pain

Single Most Likely Diagnosis

  • Musculoskeletal strain: This is the most common cause of lower left lumbar region pain, often resulting from overuse, poor posture, or direct injury to the muscles and ligaments in the lower back.

Other Likely Diagnoses

  • Lumbar disc herniation: Herniation of the intervertebral disc can cause pain in the lower back, especially if the herniation compresses or irritates nearby nerves.
  • Degenerative disc disease: Wear and tear on the spinal discs can lead to lower back pain, as the discs lose their cushioning ability and may irritate surrounding nerves.
  • Sacroiliitis: Inflammation of the sacroiliac joints, which connect the sacrum to the ilium bones, can cause pain in the lower back, including the lumbar region.
  • Osteoarthritis: Wear and tear on the joints in the spine can lead to pain and stiffness in the lower back.

Do Not Miss Diagnoses

  • Kidney stones: Pain from kidney stones can radiate to the lower back and may be severe, making it crucial to consider this diagnosis to avoid missing a potentially serious condition.
  • Pyelonephritis: Infection of the kidney can cause severe back pain, fever, and other systemic symptoms, requiring prompt medical attention.
  • Aortic aneurysm or dissection: Although rare, these conditions can present with sudden, severe back pain and are medical emergencies.
  • Spinal infection or abscess: Infections such as osteomyelitis or epidural abscess can cause severe back pain and require immediate medical intervention.

Rare Diagnoses

  • Spinal tumors: Both benign and malignant tumors can cause lower back pain, although they are less common than other causes.
  • Cauda equina syndrome: A rare condition where the nerves in the spinal canal are compressed, leading to severe pain, numbness, and potentially permanent nerve damage if not promptly treated.
  • Osteonecrosis of the spine: Also known as avascular necrosis, this condition involves the death of bone tissue due to lack of blood supply and can cause back pain.
  • Spondylolisthesis: A condition where one of the vertebrae slips out of place onto the vertebra below it, which can cause lower back pain and may require surgical intervention.
