Lower Back Pain

Overview of Lower Back Pain

Lower back pain is one of the most common health complaints that affect people of all ages, impacting day-to-day activities and quality of life.

The lower back, also known as the lumbar region comprises vertebrae, muscles, ligaments, and nerves that work together to support body weight and movement. Lower back pain can develop when these structures experience strain, injury, or inflammation.

What is Lower Back Pain?

Lower back pain is typically defined as pain or discomfort localized in the lumbar region, below the ribcage and above the legs. It can be acute (lasting a few days to weeks), subacute (lasting 4 to 12 weeks), or chronic (lasting more than 12 weeks).

The pain may range from a dull ache to a sharp, stabbing sensation and can vary in intensity. While most cases of lower back pain are not severe and can be managed with simple treatments, in some cases, it may indicate an underlying medical condition that requires professional attention.

Common Characteristics of Lower Back Pain

• Localized Pain: The pain may stay confined to the lower back or radiate to the hips, thighs, or legs.
• Limited Mobility: Movements like bending or twisting can become difficult.
• Muscle Spasms: In some cases, muscle spasms can cause sudden and intense pain.
• Chronic Pain: Persistent pain that lasts for several weeks or months.

Types of Lower Back Pain

Mechanical Lower Back Pain

• Pain results from the way the spine, muscles, discs, and ligaments fit together and move.
• Causes: Poor posture, muscle strain, disc degeneration.

Non-Mechanical Lower Back Pain

• Pain that is not related to the structural integrity of the spine.
• Causes: Infections, tumors, or conditions like ankylosing spondylitis.

Diagnosis and Tests for Lower Back Pain

Proper diagnosis of lower back pain is essential to identify the underlying cause and determine the best treatment plan. While many people may try to manage mild pain at home, consulting a healthcare professional for an accurate diagnosis is recommended, especially for persistent or severe pain. Here’s how lower back pain is diagnosed:

Initial Medical Evaluation

When you visit a healthcare professional, they will first conduct a comprehensive medical history and physical examination.

Medical History

• Symptoms Description: You will be asked to describe the location, intensity, and duration of the pain, as well as any activities or movements that worsen or alleviate it.
• Previous Medical Issues: Any history of back problems or conditions that could contribute to pain, such as injuries or chronic illnesses, will be discussed.
• Lifestyle and Daily Activities: Your doctor may ask questions about your job, exercise routine, and posture habits to determine if these could be contributing factors.

Physical Examination

During the physical exam, the doctor may check for:

• Range of Motion: Assessing how far you can move in different directions.
• Tenderness and Pain Points: Identifying areas that are sensitive or painful to the touch.
• Reflexes and Strength: Evaluating reflex responses and muscle strength to determine if nerves are affected.

Imaging Tests for Lower Back Pain

If the initial assessment suggests that further investigation is needed, the doctor may order imaging tests. These tests help visualize the spine and surrounding tissues.

Common Imaging Techniques

• X-rays: Useful for detecting bone abnormalities, fractures, or spinal alignment issues. However, they do not show soft tissues like muscles or discs.
• MRI (Magnetic Resonance Imaging): Provides detailed images of both bones and soft tissues, such as muscles, discs, and nerves. This is often used to detect herniated discs, spinal stenosis, or tumors.
• CT Scans: A more detailed form of X-ray that can create cross-sectional images of the spine, providing more information on bone structures and potential damage.
• Bone Scans are sometimes used to detect bone infections or conditions such as osteoporosis.

Specialized Tests

In some cases, more specific diagnostic tests may be performed to assess nerve function or the extent of any underlying issues.

Types of Specialized Tests

• Electromyography (EMG): Measures the electrical activity of muscles and nerves. It can identify conditions like nerve compression or damage.
• Nerve Conduction Studies: Often conducted alongside EMG, this test measures how quickly electrical impulses travel through nerves.
• Discography: Involves injecting a contrast dye into a spinal disc to assess whether it is the source of pain.

Laboratory Tests

If an infection, inflammation, or other systemic condition is suspected, the doctor may recommend laboratory tests.

• Blood Tests: Can help detect markers of infection or inflammation, such as an elevated white blood cell count or C-reactive protein (CRP).
• Urine Tests: Used to rule out kidney issues that could cause referred pain in the lower back.
