Anatomy of Spinal Discs

Spinal discs are situated between the vertebrae in the spinal column. Each disc is composed of two distinct parts: the nucleus pulposus, which is the soft, jelly-like center designed to absorb shock and pressure, and the annulus fibrosus, a tough outer ring that adds structure and strength to the disc. This combination allows spinal discs to cushion the vertebrae effectively during various movements and activities.

Causes and Risk Factors

Several possible causes and risk factors can contribute to a herniated disc. These include:

  • Age-related wear and tear (disc degeneration)
  • Strain from lifting heavy objects improperly
  • Traumatic injury to the spine
  • Repetitive motions and poor posture
  • Genetics 
  • Obesity
  • Smoking, which can decrease oxygen levels in the body and impair disc healing


Symptoms of a herniated disc vary depending on the location and severity. The following symptoms may indicate a herniated disc:

  • Pain in the back, buttocks, thigh, calf, or arm
  • Numbness or tingling in body parts served by the affected nerves
  • Muscle weakness affecting balance and mobility
  • Shooting pain with certain movements or positions

If you experience any of these symptoms, it is important to see a doctor for an accurate diagnosis and appropriate treatment.

Diagnosing Herniated Discs

Diagnosing herniated discs involves a multifaceted approach. Initially, a detailed medical history is taken, followed by a physical examination to identify specific pain points and evaluate nerve function. Imaging tests such as MRI or CT scans are utilized to determine the location and severity of the herniation. Additionally, nerve function is assessed through nerve tests like electromyography (EMG), which helps evaluate any nerve damage associated with the herniated disc.

Treatment Options

Conservative Care

Conservative treatment options are often the first line of defense against herniated discs and may include:

  • Physical therapy to strengthen the back and abdominal muscles
  • Pain medications like NSAIDs or oral steroids
  • Lifestyle modifications, including weight loss and ergonomic adjustments
  • Epidural steroid injections for pain relief

Surgical Treatment

Surgery for herniated discs may be considered if conservative treatments fail to improve symptoms. Surgical intervention usually focuses on removing the protruding disc material that is pressing on nerves or the spinal cord. The decision for surgery is based on the severity of symptoms, overall health, and response to non-surgical treatments.
