Lower Back Pain and Sciatica: Types, Causes, and Treatments

Lower back pain is one of the most common health complaints in adults, affecting millions of people worldwide. When this pain radiates down the leg, it may be due to sciatica, a condition caused by irritation or compression of the sciatic nerve. At South Miami Neurology, our team of seven board-certified neurologists offers expert evaluation and treatment for patients experiencing back pain. We also treat sciatica and a range of neurological conditions.

What Is Lower Back Pain?

Lower back pain refers to discomfort localized in the lumbar region of the spine. This region bears much of the body’s weight. While many cases are short-lived, others can become chronic, interfering with daily activities and quality of life. Low back pain can present as a dull ache, sharp stabbing pain, stiffness, or even numbness and tingling if nerves are involved.

Causes of Low Back Pain

Several conditions may contribute to low back pain, including:
• Muscle Strain or Ligament Sprain – Often caused by heavy lifting, sudden movements, or poor posture.
• Degenerative Disc Disease – Age-related wear and tear on spinal discs that leads to chronic pain.
• Herniated or Bulging Discs – When spinal discs press on nearby nerves, causing pain and inflammation.
• Arthritis of the Spine – Inflammation in spinal joints leading to stiffness and pain.
• Spinal Stenosis – Narrowing of the spinal canal that compresses nerves.
• Trauma or Injury – Accidents, falls, or sports injuries can cause acute or long-term back pain.

What Is Sciatica?

Sciatica occurs when the sciatic nerve, the largest nerve in the body that runs from the lower back through the hips and down the legs, is compressed or irritated. The hallmark symptom is radiating pain that travels from the lower back into the buttocks and down one leg. Some patients may also experience numbness, tingling, or muscle weakness.

Common Causes of Sciatica

• Herniated Disc – The most frequent cause, where disc material presses against the sciatic nerve.
• Bone Spurs – Bony growths on the spine that narrow the nerve pathways.
• Spinal Stenosis – Narrowing of the spinal canal that pinches the sciatic nerve.
• Piriformis Syndrome – Tightening or spasms in the piriformis muscle, located in the buttock, that irritate the sciatic nerve.
• Injury or Trauma – Accidents that directly affect the lower spine or pelvis.

Types of Low Back Pain and Sciatica

Back pain and sciatica are typically classified as:
• Acute Pain – Lasts a few days to weeks, often caused by strain or injury.
• Chronic Pain – Persists longer than 12 weeks, often linked to degenerative conditions.
• Neuropathic Pain – Results from nerve damage or irritation, such as sciatica.
• Mechanical Pain – Related to movement, posture, or the musculoskeletal system.

Identifying the type and source of pain is essential to creating an effective treatment plan.

Diagnosis

At South Miami Neurology, our neurologists use a thorough approach to diagnose the root cause of back pain and sciatica. This may include:
• Medical history and physical examination
• Neurological evaluation to check reflexes, strength, and sensation
• Imaging studies such as MRI, CT scans, or X-rays
• Electrodiagnostic tests to assess nerve function

Treatment Options

Treatment for low back pain and sciatica varies depending on the severity and underlying cause. Many patients find relief with conservative care. However, others may need advanced interventions.

Non-Surgical Treatments
• Medications – Pain relievers, anti-inflammatories, and muscle relaxants to reduce discomfort.
• Physical Therapy – Exercises to strengthen muscles, improve flexibility, and support spinal health.
• Lifestyle Modifications – Posture correction, weight management, and ergonomics to prevent recurring pain.
• Heat and Cold Therapy – Helps reduce muscle tension and inflammation.
• Epidural Steroid Injections – Reduce nerve inflammation and provide temporary relief.

Advanced and Surgical Options
If conservative treatments fail, surgical intervention may be considered as an option. Options include:
• Discectomy – Removal of herniated disc material pressing on the nerve.
• Laminectomy – Removal of part of the vertebra to relieve nerve compression.
• Spinal Fusion – Stabilizes the spine in cases of severe degeneration or instability.

Living with Low Back Pain and Sciatica

Back pain and sciatica can be frustrating and painful. Many patients improve with the right treatment plan. Preventative strategies, including regular exercise, maintaining a healthy weight, practicing good posture, and avoiding heavy lifting, can reduce the likelihood of recurrence.
