Back pain is a widespread issue that affects many individuals. While general practitioners often manage various forms of back pain, neurologists offer specialized care when the pain involves the nervous system. A neurologist is a medical doctor who focuses on diagnosing, treating, and managing disorders of the brain, spinal cord, and nerves. This specialization makes them particularly suited for cases where back pain has a suspected or confirmed neurological component.
When to Consult a Neurologist for Back Pain
Consulting a neurologist for back pain becomes appropriate when symptoms or circumstances suggest involvement of the nervous system. Persistent back pain that does not improve with conventional treatments, such as rest, physical therapy, or general pain medication, is a key indicator. Neurologists can provide a more in-depth evaluation for such cases.
Specific “red flag” neurological symptoms also warrant a neurologist’s assessment. These include pain that radiates down the leg, commonly known as sciatica, especially if accompanied by numbness, tingling, or weakness in the leg or foot. A sudden loss of bladder or bowel control, known as cauda equina syndrome, is a medical emergency that requires immediate attention from a neurologist or emergency services. Other concerning signs are progressive weakness in the legs or feet, sudden and severe back pain following an injury, or back pain accompanied by fever, chills, or unexplained weight loss. Often, a primary care physician will make the initial referral to a neurologist.
How Neurologists Diagnose Back Pain
Neurologists begin the diagnostic process for back pain with a thorough patient history and a physical examination. This examination places particular emphasis on the neurological assessment, which involves checking reflexes, sensation, muscle strength, gait, and coordination to identify any nerve or muscle dysfunction.
Imaging studies are frequently used to visualize the spine and surrounding structures. Magnetic Resonance Imaging (MRI) is a valuable tool as it provides detailed images of soft tissues like discs, nerves, and the spinal cord. It is particularly useful for detecting conditions such as herniated discs, spinal stenosis (narrowing of the spinal canal), and tumors that might be pressing on nerves. Computed Tomography (CT) scans offer detailed views of bone abnormalities and fractures, and are often used when MRI is contraindicated or in emergency situations. CT scans can also help identify disc degeneration, ruptured discs, and spinal stenosis.
Specialized nerve tests further aid in pinpointing the source of neurological back pain. Nerve Conduction Studies (NCS) measure the speed and strength of electrical signals as they travel through nerves, helping to detect nerve damage or compression. Electromyography (EMG) assesses the electrical activity of muscles, which can reveal nerve or muscle dysfunction. While X-rays primarily show bone structure, they may be used to identify fractures or spinal alignment issues. Blood tests might also be ordered to rule out inflammatory conditions or infections that could contribute to back pain.
Treatment Strategies for Neurological Back Pain
Neurologists prioritize conservative, non-surgical approaches for managing neurological back pain. Medication management often includes prescriptions specifically for neuropathic pain, such as gabapentin or pregabalin. Muscle relaxants and anti-inflammatory drugs may also be used to alleviate symptoms.
Referrals to physical therapy are a common part of the treatment plan. Physical therapists work to strengthen core muscles, improve posture, and enhance flexibility. Injections can provide targeted pain relief and reduce inflammation around affected nerves. These include epidural steroid injections, which deliver anti-inflammatory medication directly into the space around the spinal nerves, and nerve blocks, which temporarily interrupt pain signals from specific nerves.
Lifestyle modifications also play a role in managing neurological back pain. Neurologists may advise on ergonomic adjustments, regular exercise tailored to the individual’s condition, and weight management to reduce stress on the spine.
While neurologists do not perform surgery, they work closely with neurosurgeons or orthopedic spine surgeons when conservative treatments prove ineffective or when there is significant neurological deficit, such as severe weakness or cauda equina syndrome. Common surgical procedures for back pain include discectomy, which removes parts of a herniated disc; laminectomy, which involves removing a section of bone to relieve pressure on nerves; and spinal fusion, where vertebrae are joined to stabilize the spine. Neurologists play a role in the decision-making process for surgical intervention and may also be involved in post-operative care.
